Principal Investigator  

Gavin M. Bidelman, PhD (CV) (PubMed) (Google Scholar) (Research Gate) is an auditory cognitive neuroscientist who uses neuroimaging and data science tools (EEG/ERPs, psychophysics, computational modeling, machine learning) to investigate foundational properties of auditory perception and cognition. The work includes elements of both basic research and clinically motivated inquiry. Lab studies proceed on three main fronts: (1) understanding the neurocomputations involved in the perception-cognition and novel learning of speech and musical sounds—with current emphasis on auditory categorization; (2) a neuroethological approach characterizing the upper bounds of brain plasticity via study of listeners with extraordinary auditory expertise (e.g., musicians, bilinguals); and translational work (3) examining changes in neurophysiological coding across the lifespan in both normal and clinical populations (hard of hearing, mild cognitive impairment). The lab is funded by the NIH/NIDCD.  

 

PhD students   

 

 

Jessica MacLean,MM, MT-BC, joined the lab in Fall 2022 as a dual PhD student in SLHS and Neuroscience at Indiana University. She holds a Master of Music in Music Therapy with Undergraduate Equivalency (University of Miami) and a Bachelor of Science in Music (violin) with an Outside Field in Neuroscience (Indiana University). Most recently, Jessica served as core project manager for a multi-site R01 trial out of the IU School of Nursing in Indianapolis investigating biologic mechanisms of active music engagement in pediatric oncology (PI: Sheri Robb, PhD, MT-BC). She also worked as a research assistant in the Brainvolts Auditory Neuroscience Lab at Northwestern University (PI: Nina Kraus, PhD). Jessica’s research interests include clinical applications of music for speech and language outcomes with a focus on gaining deeper understanding of the associated neural mechanisms.

 

 

 

 

Rose Rizzi is a dual PhD student in SLHS and Neuroscience at Indiana University. She earned her BS in Cognitive and Behavioral Neuroscience at Virginia Tech in 2020. Her research interests include neuroplasticity, neurostimulation, and auditory attention.

Jane Brown is a PhD student in Communication Sciences and Disorders with a Neuroscience focus at the Unversity of Memphis. Originally from Baltimore, Maryland, Jane earned her BA in Biopsychology, Cognition, and Neuroscience from the University of Michigan in 2017. Before coming to Memphis, she spent two years in the Avian Behavioral Neuroscience Lab at the University of Maryland, where she studied auditory perception in songbirds. Her research interests include psychoacoustics and music-based neuroplasticity, and her current work is investigating the effects of familiarity in background music on speech listening.  Email: jbrown64@memphis.edu

 

AuD students  

Alexandria Sisson, B.S., joined the lab in Fall 2022 as a first year AuD student at Indiana University. She holds a Bachelor of Science in Communication Disorders and Sciences and Minor in Neuroscience from Eastern Illinois University. Most recently, Alexandria served as a research assistant in the Hearing Aid Laboratory at Northwestern University (PI: Pam Souza, PhD), as well as the Auditory Research Laboratory at Northwestern University (PI: Sumitrajit Dhar, PhD., Mary Meskan, PhD.). Alexandria’s research interests include cognitive decline and language perception, neural processing of speech and language, and auditory psychophysics.

 

Undergraduate students

Jack Stirn joined the lab in Fall 2022 as an undergraduate student studying Neuroscience and Linguistics. Jack is in the Cox Research Scholars program at IU. His research interests include psycholinguistics, pragmatics, and speech perception. 

 

Hanah Bertram. I am an undergrad majoring in Speech, Language, and Hearing Sciences with a minor in Psychology. My interests include neural processing of speech & language and speech & auditory perception. I am also a part of the Speech Production and the Neural Research lab at Indiana University.
