How was your first year at the Department of Speech and Hearing Science here at AHS?

Mariana: My first year was a period of growth and adaptation as I became familiar with the university and the Department of SHS. I have been fortunate to receive consistent support from colleagues and departmental staff, which greatly eased this transitional period and helped me navigate new academic and administrative environments.

This year was also dedicated to establishing my laboratory, the Neuro+Swallowing Research Lab, and laying the foundation for my future research program. Setting up the lab allowed me to plan my next steps, define research priorities, and begin shaping a trajectory that aligns with my long-term academic goals, while learning to adapt to the challenges and opportunities of a new institutional setting.

When did you first become interested in studying swallowing physiology and disorders, and why have you stuck with that topic in your research?

My initial interest in swallowing developed during my specialization in speech-language pathology in neurology, when I had the opportunity to conduct swallowing assessments and provide treatment for individuals with swallowing disorders, known as dysphagia, related to neurological diseases.

I was fascinated by the complexity of the swallowing process—something we do countless times a day without even thinking about it. What intrigued me most was how such an automatic act relies on the intricate coordination of more than 30 muscles (and many other structures), several nerves, and brain structures. The interaction among all the swallowing structures, along with the brain and breathing, felt like solving puzzles, and this challenge sparked my curiosity and passion for learning more about the mechanisms behind swallowing and how to best support patients with these difficulties.

As a clinically trained speech-language pathologist, I have observed the devastating impact of swallowing disorders on individuals and their families. This experience has motivated me to integrate my clinical expertise and research background in the investigation of swallowing physiology, particularly the interaction between brain-swallowing and breathing-swallowing, to advance rehabilitation approaches that enhance swallowing ability, improve patient care and enhance the quality of life for individuals with dysphagia and their families.

You’ve described dysphagia as an “invisible” disorder. For the folks you’ve worked with, how does dysphagia impact their quality of life?

Swallowing is a critical process for life. We need to eat and drink for adequate nutrition and hydration. However, we also eat and drink for pleasure and comfort. Eating is a highly social activity. Therefore, the impacts of swallowing disorders or dysphagia are not restricted to the physical health domain, such as inadequate food or liquid intake, resulting in malnutrition, dehydration, or unintended weight loss.

Individuals with dysphagia face psychological, emotional, and social impacts, including fear of eating, embarrassment, loss of enjoyment when they cannot eat or drink certain foods, and reduced social participation in cultural events or family gatherings where eating is central. The limited ability to share a meal may weaken family and community bonds.

Which therapeutic interventions can work for those living with dysphagia?

Therapeutic interventions for dysphagia aim to improve swallowing safety—preventing food or liquid from entering the airway—and efficiency: ensuring adequate passage of food from the mouth to the stomach. Importantly, interventions are tailored to individual needs and target specific impairments evident in each person. Interventions may include compensatory strategies, such as head adjustments and dietary modifications, to reduce the risk of airway invasion, as well as rehabilitative exercises to strengthen the swallowing muscles, improve the movement of swallowing structures, and enhance the coordination of the swallowing process. Additionally, rehabilitative exercises can be paired with other therapeutic modalities, such as neuromuscular electrical stimulation and brain stimulation.

Illinois researchers aim to develop more realistic hearing tests to improve clinical outcomes

July 14, 2025 | Adelyn Mui

Imagine sitting in a busy café, struggling to follow a conversation as voices and background clatter blend together. For many people with hearing loss, this is a daily challenge—yet traditional hearing tests, conducted in silent rooms with isolated tones, fail to reflect these real-world difficulties. At the University of Illinois, a team of researchers is working to bridge that gap by developing more accurate and meaningful hearing assessments that simulate everyday listening environments. 

Sadie Braun, an audiologist and clinical assistant professor in the Department of Speech and Hearing Science in the College of Applied Health Sciences, is the team’s primary investigator and recently received a $30,000 pilot grant from the Center for Health, Aging, and Disability. She is working with Dan Fogerty, an SHS associate professor, on a project titled “Creation of Speech-in-Noise Profiles for Clinical Fitting of Hearing Technologies.” 
 
The project has two goals, the first being to analyze and better understand speech-in-noise testing results from clinical environments. 

“Instead of simply pressing a button when you hear a tone, we’re trying to get more out of tests that already exist which mirror real-world scenarios,” Braun said. “For example, it is fairly common now to play full sentences while background voices are talking at the same time—more like what someone might hear at a party or in a restaurant. We want to use these results to help understand the nuances in what causes understanding-in-noise difficulties on an individual basis.” 

The second goal of the project goes a step further: not just measuring how many mistakes a person makes during a hearing test, but understanding what kind of mistakes—and why they happen. 

“Right now, clinical hearing tests can tell you that someone misunderstood a sentence, but not how they misunderstood it,” Fogerty said. “Our approach focuses on the types of errors people make and the conditions under which those errors occur.” 

By analyzing these mistakes—called error profiles—the team hopes to gain new insights into what’s actually causing the difficulty. For example, one person might confuse similar sounds, like saying “cat” instead of “cats,” which could suggest a problem with sound clarity. Another person might only repeat the second half of a sentence, pointing to a possible cognitive issue like memory or processing speed. 

“We’re identifying patterns across different types of errors,” Braun said. “Then we compare those patterns with results from standard hearing tests to see if there are connections. That could help us predict which patients need which kinds of interventions.” 
 
Data collection will begin in the fall and participants will come from patients who come to the Audiology & Speech-Language Pathology Clinic and have consented to their audio recordings being used for this study. Braun said the tests focus more on adults, primarily those in their 50s and upward. 
 
With those error profiles, the team hopes to use those to improve hearing aid fittings and outcomes for patient satisfaction.  
 
“Different types of errors can have different real-life consequences,” Fogerty said. “Identifying the reasons why someone misunderstands speech will help the clinician identify recommendations to address those specific difficulties.” 

With support from CHAD, the pilot grant will allow Braun and Fogerty to gather foundational data, refine their testing protocols and begin developing detailed error profiles. Their ultimate goal is to translate this information into better hearing aid fittings, more accurate diagnoses and improved quality of life for patients. 

Looking ahead, the team plans to apply for additional funding to expand the project and validate their findings across broader patient populations. 

Braun emphasized the strength of the partnership at the core of this work. 

“This is a true collaboration between research and clinical practice,” she said. “Dr. Fogerty brings deep expertise in auditory research, while I bring the day-to-day clinical experience. Together, we’re approaching the same problem from different angles—and that’s what gives this project real potential to move the field forward.”

2025 Sapora Symposium: Honoring a century of legacy at Huff Hall

May 22, 2025 | Vince Lara-Cinisomo

Themes of visionary leadership and George Huff were briefly overshadowed by Grimace

The theme of the 2025 Sapora Symposium was visionary leadership, coinciding with the 100th anniversary of Huff Hall and paying tribute to the legacy of George Huff. Only one thing could potentially overshadow that, and it is purple and lovable: Grimace.

The iconic McDonald’s character—who’s ostensibly a tastebud—made his appearance during one of the final Sapora panels on March 28 at the Armory. Grimace’s appearance coincided with a panel on viral marketing. Grimace became a good luck charm for the New York Mets after throwing out the first pitch at a game in June 2024, leading to a winning streak and a purple seat dedicated to him at Citi Field. 

But beside the big, purple spectacle, this year’s symposium carried greater significance as it coincided with the Huff centennial, a cornerstone of Illini academics and a testament to the university’s rich sports heritage. The event celebrated not only a century of excellence in sports and recreation but also paid tribute to the enduring legacy of George Huff, the visionary coach and administrator who transformed athletics at Illinois and beyond.

The Sapora Symposium was created and developed by the alumni advisory board of the Department of Recreation, Sport and Tourism in honor of the Department’s founder, Dr. Allen Sapora. Sapora was a cornerstone to the education and careers of many of our alumni. In recent years, the department has hosted the likes of the Stanley Cup, Governor J.B. Pritzker, Theo Epstein, and celebrated the lives of Illini legends Lou Henson, Red Grange and Theresa Grentz.

“Sapora is one of the signature components of the RST undergraduate experience,” said Clinical Associate Professor Mike Raycraft, who created the course. “It is always exciting to recruit high profile guests and inspire students to consider classroom knowledge in the context of industry leaders and influencers.”

The spring 2025 series was presented by The Specialized Marketing Group Inc., a global sports, promotional and experiential marketing company.

“Not only is this an incredible opportunity for students to learn from and connect with some of the most influential, successful people in Recreation, Sports and Tourism, it gives those of us who are already in the industry the opportunity to speak directly to the youth that will shape the future of our business,” said TSMGI founder and CEO Jordan S. Bressler. “We are thrilled to be a part of something that allows students the unique opportunity to gain invaluable knowledge and perspective as they determine what route they may wish to take.”

“Sapora is one of the signature components of the RST undergraduate experience.”

Mike Raycraft

This year’s symposium is particularly noteworthy as it honored George Huff, a legendary figure whose influence continues to resonate within the Illinois community. As the university’s athletic director from 1901-36, Huff played a pivotal role in shaping modern college athletics. His foresight led to the construction of Memorial Stadium and the establishment of key athletic programs that set a precedent for institutions nationwide. Under his leadership, Illinois became a powerhouse in collegiate sports and his innovations in athletic administration laid the foundation for modern sports management practices.

Huff Hall has stood as a beacon of athletic excellence for a century. Originally constructed in 1925 as the Men’s New Gym, the facility was later renamed in honor of Huff to recognize his contributions to the university’s athletic legacy. Over the decades, Huff Hall has hosted countless historic moments, from a speech by First Lady Eleanor Roosevelt during World War II to championship basketball games to landmark wrestling matches to dance marathons, embodying the spirit of competition and community that Huff championed throughout his career.

The 2025 Sapora Symposium kicked off with an evening with RST alums Dee Brown and James Augustine at the Hubbard Inn, included a weekly Zoom webinar speaker series, continued with an all-day professional development event on campus and concluded with a site visit examining opportunities and impacts related to the WNBA’s Chicago Sky, Wintrust Sports Complex at the Village of Bedford Park, and MLB’s Chicago White Sox in April. In addition, it also included a pickleball fundraising event to benefit the Cunningham Children’s Home.

“The platform that Mike has created creates so much opportunity for amazing conversations and discussions,” said Carly Eilian, vice president of public relations and communications at TSMGI, based in Deerfield, Illinois. “We love being a part of something that allows students the unique opportunity to gain invaluable knowledge and perspective as they determine what route they may wish to take.”

Eilian said the symposium gives students the opportunity to learn from some of the most influential people in the recreation, sport and tourism industries, and that it allows people in the industry a direct pipeline to the next generation.

“We hope to continue the momentum of the symposium making it a must-attend event for our industry and prospective industry members,” she said.

Beyond the academic and professional development opportunities, the symposium also served as a celebration of the Illinois spirit. Alumni, faculty and students came together to honor Huff Hall’s centennial, reflecting on its storied past and looking ahead to its future role in fostering athletic and academic excellence. As the University of Illinois celebrates the 100th anniversary of Huff Hall, the 2025 Sapora Symposium stands as a fitting tribute to a man whose impact on collegiate athletics and sports management remains unparalleled.

As a testament to that, RST has established the Huff Society Fund. Gifts to the Huff Society Fund empower students in the Recreation, Sport, and Tourism program by supporting scholarships, hands-on learning opportunities, and event costs. Your generosity helps make transformative experiences—such as guest speaker events, experiential trips, and transportation—accessible to all students. 

Donations to the Huff Society Fund will also allow the department to recognize, recruit and retain top students while preparing them to become future leaders in the field. Donors to the Huff Society Fund join a passionate community of supporters dedicated to shaping the next generation of RST professionals

SHS researchers bridge research and real life

May 20, 2025 | Vince Lara-Cinisomo

The work at the College of Applied Health Sciences doesn’t stay in the lab—it transforms lives. Faculty such as Meaghan McKenna and Laura Mattie exemplify the college’s commitment to bridging research with community impact. Whether developing interventions for literacy in schools or building relationships with families of children with disabilities, they show how academic insights can create tangible benefits.

Mattie joined the faculty in the Department of Speech and Hearing Science in 2015. Now an associate professor, she has spent the past nine years working on research with her colleagues in SHS as the principal investigator in the Development in Neurogenetic Disabilities Lab. She said her time spent at the department has led to close relationships, both personal and professional.

“The interdisciplinary nature of the department, the university and the college really has helped me to build more collaborations, and I think that’s one of the key things to being successful in my field,” Mattie said. “Some of my collaborators are my closest friends.”

Mattie’s fall semester class, titled Children with Neurodevelopmental Disorders Across Communication Contexts, covers the development of social and communication skills in children with various neurodevelopmental disorders that her research is focused on as well. Her current research, which primarily concerns children with fragile X syndrome and Down syndrome involves longitudinal studies that require a level of personal connection with families of children partaking in her studies. 

For Mattie, being a new mom to two young girls has offered a fresh perspective on her research.

“As we’re getting closer to the end of the project and thinking of what to do next, the mom in me led to the thought, ‘How do we get information to moms and clinicians quicker?”’

Mattie said building relationships with families really allowed researchers to value their thoughts and experiences.

“I want to partner with families and clinicians—and we found this evidence that we think is helpful—but how can we package the information so they can use it every day; how can we really make it accessible for them, and instead of getting it to them in 10-15 years (the current research-to-practice gap), get it back to them quicker?”

McKenna isn’t just one of the most recent additions to the SHS as an assistant professor. She also has years of experience as a speech-language pathologist and a passion for connecting with districts, schools and educational professionals about solving problems of practice corresponding to literacy and multi-tiered systems of support.

“Forming partnerships and relationships is the most important thing I do,” she said.

Working in SHS is a position that is far from stationary: McKenna’s work pulls her across not only campus, but into surrounding cities and school districts where she aims to narrow the gap between research and practice. She currently partners with her colleague Amber Ray in the Department of Special Education and Holy Cross School in Champaign on writing intervention research. 

McKenna has also joined three other schools and districts who connected with her about their mutual interest in solving problems of practice corresponding to writing. In Danville, she is collaborating with the curriculum department and classroom teachers as K-2 instructional guides are created that highlight daily writing activities aligned with the core curriculum and evidence-based practices. In Blue Ridge, Illinois, professional development sessions that address writing instructional priorities identified by classroom teachers are held monthly. In Chicago, a Pre-K-8 school formed an instructional leadership team committed to vertical alignment of how the writing process (cycle) is taught and student writing is evaluated.

“I think it’s important for us to bridge what we’re doing in research and think about how it translates into practice,” she said. “I don’t think it’s productive to be in a research lab all day or writing papers if it doesn’t have any impact on the community or individuals who are going to be applying the findings. The opportunity to co-learn with schools and districts across the state (who are) committed to prioritizing writing has been the highlight of my second year in Illinois.”

Fogerty-led research team tackles hearing health disparities with innovative at-home assessment

May 20, 2025 | Adelyn Mui

Research for a gap in treatment for hearing in noisy environments has been active for decades

Approximately 37.5 million adults in the United States experience hearing loss. A team from the University of Illinois is working to alleviate barriers in accessibility and affordability to hearing health care.

Dan Fogerty, an associate professor in the Department of Speech and Hearing Science in the College of Applied Health Sciences, recently received two grants to support his project, titled “Empowering Illinois Communities for Better Hearing Health.” The project is focused on improving access to hearing screening through an at-home assessment and focusing on a primary hearing complaint: difficult hearing in noisy environments. 

One grant is from the Chancellor’s Call to Action Research Program. This program aims to empower the university community to address the greatest challenges facing our society and seek new solutions. The second grant, from Campus Research Board, supports the work done to create the self-administered hearing assessment. Total funding from the grants amounts to just under $100,000.

“Current hearing screening methods, which consist of detecting simple tones in quiet, often fail to address real-world challenges,” Fogerty said. “Hearing screening can be improved by more accurately assessing the listening difficulties that people complain about and may be more motivated to address.”

Research for this gap in treatment for hearing in noisy environments has been active for decades, Fogerty said. 

“It involves both technology-focused solutions, such as advanced hardware and signal processing to reduce noise and enhance speech, as well as aural rehabilitative strategies involving education and training,” Fogerty said. “The focus of this project is to help identify the specific challenges that an individual might have when listening in noisy environments in order to customize the collection of strategies that might be most useful for them.”

A team consisting of researchers from the Audiology and Speech-Language Pathology Clinic, the College of Agricultural, Consumer and Environmental Sciences and the Office of the Vice Chancellor of Research and Innovation will develop and implement an at-home assessment, including a smartphone app. Over the course of the project, they will also examine implementation in the lab, the audiology clinic and in communities across the state.

Fogerty said this combined interdisciplinary approach will help them tackle accessibility and affordability issues.

Hearing screening can be improved by more accurately assessing the listening difficulties that people complain about and may be more motivated to address.

Associate Professor

“Our partnership with the audiology clinic ensures the translation of this research into clinical practice. ACES brings expertise in community engagement, specifically through the Illinois Extension offices which will facilitate public education and access,” Fogerty said. “OVCRI contributes research infrastructure and computational expertise through NCSA.”

NCSA, the National Center for Supercomputing Applications, will support the development of a hearing app that will expand access to the innovative hearing assessment. The high prevalence of smartphones allows online and app-based testing to be possible.

Fogerty said addressing hearing disparities is a priority because untreated hearing loss has widespread medical, social and economic consequences. Adults in underserved communities can be far away from hearing centers and often face shortages in hearing services with healthcare providers. Economic barriers, such as travel costs or time away from work, may also interfere with affordability.

“Mobile self-administered hearing assessments, downloadable to a smartphone, will literally put personalized hearing health information at our fingertips,” Fogerty said.

At-home hearing assessments are innovative because they enable advanced hearing care remotely, removing barriers and costs associated with in-person clinic visits.

“These tests can be conducted anywhere at any time,” Fogerty said. “This also increases the likelihood of patient follow-up and compliance with testing recommendations due to the convenience and flexibility of the assessment.”

Hearing aid use has been reported as low as 8.6% among adults with some hearing handicap. Fogerty said there are a variety of reasons for this statistic. 

“Gaps in insurance coverage and perceived social stigma may contribute,” Fogerty said.  “Underestimating hearing difficulties, limited awareness of potential treatment options, or difficulty accessing services are other common reasons. Our self-assessment is designed to address some of these factors.”

Even with some over-the-counter hearing aid options, OTCs are still relatively new and many barriers remain.

“Limited awareness of hearing difficulty or treatment, stigma, out-of-pocket costs [are still factors],” Fogerty said. “OTCs are also only intended for use by adults with perceived mild to moderate hearing loss without other medical conditions.”

The funding for this project will start in July and last one year, with the home-based assessments planned to start in early 2026.  Fogerty anticipates recruiting 200 adults across all study phases, which will include testing in the laboratory, audiology clinic and community.

The science of sound: Understanding how the brain helps us hear in noise

May 20, 2025 | Vince Lara-Cinisomo

A new study aims to deepen our understanding of how the brain influences our ability to distinguish speech amid background noise

For millions of people worldwide, hearing loss is not simply a matter of volume but clarity—especially in noisy environments. Struggling to distinguish a single voice in a crowded restaurant, a busy office or even a family gathering is a common report among those with hearing difficulties. Researchers at the forefront of auditory science are investigating an essential but often overlooked aspect of hearing: the brain’s role in processing sound.

A study led by Department of Speech and Hearing Science Associate Professor Ian Mertes, titled “Olivocochlear Efferent Function: Associations with Hearing in Noise and Listening Effort,” aims to deepen our understanding of how the brain influences our ability to distinguish speech amid background noise. The project, supported by a three-year, $570,000 grant from the National Institutes of Health, will examine the neurological mechanisms that contribute to hearing in noise and the effort required to listen under challenging conditions.

Mertes has been interested in how the brain influences the inner ear since he was a graduate student.

Hearing is often thought of as a passive process: sound waves enter the ear, are converted into neural signals, and are sent to the brain for interpretation. However, the reality is far more complex. The auditory system has a top-down control mechanism that influences how the ear processes incoming sounds. This system, known as the medial olivocochlear efferent system, acts as a neural feedback loop that modulates auditory input.

But Mertes said there are still unanswered questions about how this system contributes to listening in everyday life. Efferent pathways originate in the brainstem and extend to the cochlea, the inner ear’s sensory organ responsible for converting sound waves into electrical signals. These pathways play a crucial role in adjusting how we hear in noisy environments. By selectively dampening background noise and enhancing speech signals, the medial olivocochlear system may improve our ability to focus on important sounds while ignoring irrelevant ones.

“My study also examines if the medial olivocochlear reflex is involved in listening effort,” he said. “Even if the medial olivocochlear reflex does not improve someone’s performance on a speech-in-noise task, it may reduce the mental resources needed to listen in background noise.”

Investigating Speech-in-Noise Recognition

The study aims to explore how variations in this top-down control contribute to an individual’s ability to understand speech in noisy settings. Researchers will work with adults who report varying levels of difficulty in hearing amid background noise. By measuring their auditory responses under controlled conditions, the team hopes to uncover patterns that link efferent function to speech recognition abilities. Mertes said that in addition to people with hearing loss, it’s estimated that up to 44 million U.S. adults have clinically normal hearing and yet report that they have difficulty hearing in noisy situations. 

“We are still trying to understand the underlying reasons for these difficulties,” he said.

Beyond understanding speech in noise, the study will also explore the cognitive effort required to listen in difficult auditory environments

Participants will undergo a series of tests assessing their ability to discern speech against different levels of background noise. These assessments will be paired with physiological measurements of inner ear and auditory brainstem activity, allowing the researchers to determine how the brain’s feedback mechanisms influence perception. By comparing individuals with and without self-reported hearing difficulties, the research team aims to identify specific deficits in the olivocochlear system that may contribute to these challenges.

“We hypothesize that medial olivocochlear reflex function will be reduced in the group that reports having significant difficulties because they have less noise reduction happening at the level of their inner ear,” Mertes said.

Measuring Listening Effort

Beyond understanding speech in noise, the study will also explore the cognitive effort required to listen in difficult auditory environments. Listening effort is a critical but often subjective aspect of hearing. Even if two individuals achieve similar results on a hearing test, one may expend significantly more mental energy to achieve the same level of comprehension.

Implications for Future Research and Interventions

The findings from this study could have significant implications for hearing health care. Currently, hearing aids and assistive devices primarily amplify sound, but they do not always enhance speech clarity in noisy environments. By better understanding the brain’s role in modulating auditory input, researchers may pave the way for new treatments or hearing aid technologies that target neural mechanisms rather than just the mechanical aspects of hearing loss.

For example, future hearing aids might be designed to simulate the brain’s natural medial olivocochlear efferent control system, selectively amplifying relevant sounds while suppressing background noise more effectively. Additionally, clinicians could use diagnostic tests based on medial olivocochlear efferent function to personalize treatment strategies, ensuring that interventions are tailored to an individual’s specific auditory processing profile.

A Step Toward Better Hearing Solutions

This study represents an important step in bridging the gap between neuroscience and audiology. By shedding light on the intricate relationship between the brain and the ear, researchers hope to improve outcomes for individuals struggling with speech-in-noise recognition.

“I’m currently focused on understanding the physiology that is involved in hearing in background noise,” Mertes said. “I’m hopeful that my work will help contribute to improved diagnosis and treatment of listening difficulties, especially for people with clinically normal hearing.”

New SHS faculty member advancing communication for individuals with disabilities

May 20, 2025 | Adelyn Mui

AAC refers to a range of methods that people use to communicate, other than spoken language

By ADELYN MUI

Savanna Brittlebank has dedicated her academic career to improving communication for individuals with complex needs. As a new faculty member in the Department of Speech and Hearing Science in the College of Applied Health Sciences, she brings knowledge and experience to the field of augmentative and alternative communication, or AAC.

AAC refers to a range of methods that people use to communicate, other than spoken language. It includes gestures, symbols, pictures, writing or use of electronic devices to express thoughts, needs and wants.

Brittlebank first became interested in AAC after working with children who had trouble communicating. She initially majored in psychology but worked extensively with individuals with disabilities. One of the reasons she decided to come to the University of Illinois is that she values the robust resources that the university has.

“There’s a lot of opportunity as well for expansion of my research because there is just a strength across different disciplines of the research that’s going on,” Brittlebank said. “The university really values that and has a lot of support to kind of push that growth as well, which drew me here. I keep learning more and more.”

Brittlebank recalled a time when she worked with a 3-year-old girl who was hearing-impaired and blind. The child also had an intellectual and developmental disability and no speech. 

“She was still developing language, and I didn’t know what to do,” Brittlebank said. “I didn’t know how to best support her communication. Whenever I spoke to my supervisors and when I looked in the research, there really wasn’t anything. I realized I wasn’t the only one who didn’t know how to help this population. I realized that’s more where my passion was, and so I went back and studied further, and I’ve focused on research on that ever since.”

Brittlebank grew up in Zimbabwe and completed her BSc Hons (comparable to a U.S. bachelor’s degree) at University of York in England before coming to the United States to complete her M.S. at Pennsylvania State University. After her M.S., she worked clinically in Wisconsin as a speech-language pathologist, then returned to Penn State for her Ph.D. From there, she made her way to Illinois as an assistant professor in SHS.

“University of Illinois is one of the most disability-friendly campuses,” Brittlebank said. “There’s so many different resources available for individuals with disabilities, and there’s so much accessibility, more so than I’ve seen in a lot of other places. That was really encouraging considering I often work with people with disabilities who have limited speech.”

Since joining the university in fall 2024, Brittlebank has been in the process of getting new projects up and running and finishing old ones. She said one of her goals is to expand the accessibility of these interventions in lower-resource communities. In late April, Brittlebank received an award from the Campus Research Board for her project titled “Communication Partner Training to Support Language Outcomes in Children with Significant Disabilities.” This intervention research will investigate the effectiveness of training communication partners (e.g., paraprofessionals, direct support staff) of young children with significant challenges in both speech and motor abilities (i.e., multiple disabilities) in an evidence-based strategy to enhance child language outcomes. 

In addition to access for lower-resource communities, Brittlebank also said that AAC is still moving forward in terms of representation for different cultures and different languages.

“AAC can be particularly challenging. I think one of the biggest barriers is access to technology,” Brittlebank said. “We can definitely support communication with photographs or with writing, but a lot of what’s out there as well is access to these computer- or tablet-like systems where you can access the internet. Families might not have it readily in the home as it’s a more costly system.”

AAC can be particularly challenging. I think one of the biggest barriers is access to technology.

Savanna Brittlebank

Assistant Professor

Brittlebank has worked on projects such as Transition to Literacy or T2L, a software that provides dynamic speech and text output upon selecting a graphic symbol. She said that traditional systems can be limiting—if every single word is not programmed, an individual cannot say everything that they want. However, the T2L feature helps support literacy by teaching individuals. 

“It’s the idea that it’s an additional support to direct literacy instruction, but it’s a great way that it can be embedded and someone can get exposure to literacy learning throughout the day,” Brittlebank said.

Brittlebank said literacy is powerful: if an individual has the alphabet, they can say anything they want. 

“Literacy, in this day and age as well—it really enables social communication and building friendships. If someone has trouble with speech, and then they have trouble with communication, that has a series of impacts from not being able to engage in education or limiting employment opportunities and limiting the ability to make friendships,” Brittlebank said. “It’s really important to make sure that individuals have access to language and communication and have appropriate access to language and communication.”

AHS students present diverse projects for Undergrad Research Week

For a freshman at the College of Applied Health Sciences, Saiesha Bollapragada’s research portfolio is impressive. 

At last week’s Undergraduate Research Symposium, the I-Health major got to present the results from her first research project, “Public Health Preparedness Among UIUC Students During Extreme Heat Conditions,” where she examined students’ awareness and handling of severe heat in the spring semester. 

She completed her study with a push from Students Pursuing Applications, Research and Knowledge, or SPARK, an AHS program that jump-starts incoming undergraduate students research experiences by pairing them with professors in the college. Bollapragada was placed with Recreation, Sport, and Tourism Associate Professor Mariela Fernandez, whose experience with urban environmental injustices fit her research topic perfectly. 

“Professor Fernandez motivated me to start this project on my own,” Bollapragada said. “There’s a lot more reading involved than I thought there was, it was a lot of work preparing for the symposium, but if it’s something you’re interested in it’s a fun process.” 

Students, faculty and staff got a taste of the findings from AHS’ budding student researchers during the AHS Undergraduate Research Expo at Huff Hall on Wednesday, April 24, where a roster of undergraduates gave poster presentations on a diverse range of research topics.

Many students spearheaded their own research projects with significant support and guidance from faculty and graduate students. Others, like a group of Speech and Hearing Science students from the Intellectual DisAbilities Communication Lab led by Associate Professor Marie Moore Channell, provided updates on long-range research projects they’ve assisted with on campus. 

Three SHS seniors, Emma Mueller, Abigail Keasler and Liz Gremer, presented initial findings from their glimpse into the Speech Accessibility Project, an ongoing research endeavor looking to make voice recognition software—such as Apple’s Siri or Amazon’s Alexa—more accessible for people with different speech patterns.

Each of the students has helped recruit participants with Down syndrome or aided vocal transcriptions from the samples they’ve collected. Under the leadership of Channell, the lab hopes to collect 240,000 voice samples from 400 participants. 

“Our poster looked into the recruiting process with that population and took a look at patterns of articulation differences exhibited by individuals with Down syndrome,” said Mueller, who transcribed vocal samples for the project. 

All three of the students met in Channell’s lab, and immediately found research responsibilities once the Down syndrome portion of the project came under Channell’s purview. 

“It’s been very rewarding, very interesting and very impactful,” Keasler said. “A lot of families in meetings or over the phone say, ‘Siri doesn’t really understand what we’re trying to say,’ so this is very important and I can’t wait to see the results of it.” 

Coming to a project affiliated with SHS with “so much publicity and so much money coming in is encouraging,” said Gremer, who has helped recruit participants and set up their first meetings for collecting voice samples. 

AHS student programs, such as the first-generation focused Mannie L. Jackson Illinois Academic Enrichment and Leadership Program (I-LEAP), were well represented in the research symposium. I-LEAP juniors Elizabeth Martinez and Aubrey Cervantes, both studying kinesiology, brought results from their research collaboration on high-intensity interval training. 

Working within KCH Professor Steve Petruzzello’s Exercise Psychophysiology Lab, the pair analyzed 25 participants’ emotional responses to high-intensity exercise, compared with their scores and symptoms of several mental health qualities: namely anxiety, depression and neuroticism. 

“We were looking at exercise adherence—how can we get more people to get more active—and we were really interested in HIIT exercise, so we put it all together in one research project,” Cervantes said. 

What they found: Participants with more symptoms of depression reported more negative affect responses during the HIIT exercise, while anxiety and neuroticism didn’t show significant predictive power, they said.

“This is my first hands-on [study] that I can call my own and Aubrey’s,” said Martinez, who’s applying to physical therapy schools. “My favorite part is meeting with the participants. It’s so fun getting to know everyone, even if there’s a lot more hours behind the desk just plugging and chugging data.”
