Biography:

Mark Sayles is an Assistant Professor at Purdue University, with a joint appointment in Biomedical Engineering and Speech, Language and Hearing Sciences. He received a B.A. degree in Natural Sciences from the University of Cambridge (UK) in 2003. He then completed a joint M.D./Ph.D. program at the University of Cambridge, graduating in 2009. His Ph.D. research focused on neural coding of speech and musical sounds in the mammalian brainstem under realistic acoustic conditions; i.e., listening environments where our ears are challenged by background noise and reverberation. He undertook surgical residency training in the UK, specializing in otorhinolaryngology and head and neck surgical oncology. Mark’s post-doctoral work was in the Department of Neuroscience at the University of Leuven, Belgium, where he evaluated the role of cochlear mechanics in binaural hearing by recording from highly specialized neurons in the superior olivary complex and applying innovative systems-identification techniques to the analysis of neural data. He was a Fulbright post-doctoral fellow at Purdue, working on auditory neural coding following hearing impairment. In 2016, he joined the faculty at Purdue as an Assistant Professor, where his laboratory investigates the relationship between brainstem single-neuron physiology and perception in normal-hearing and hearing-impaired listeners. He teaches classes in both SLHS and BME. He is a member of the Association for Research in Otolaryngology, the Royal College of Surgeons of England, the Society for Neuroscience, and the Acoustical Society of America.
