Biography:

Allison Schaser, Ph.D., CCC-SLP is an Assistant Professor in the Department of Speech, Language, and Hearing Sciences at Purdue University.  She holds a bachelor’s degree in Speech-Language Pathology from Miami University in Ohio and a master’s degree in Communication Sciences and Disorders from the University of Wisconsin-Madison.  She earned her Ph.D. in Communication Sciences and Disorders from the University of Wisconsin-Madison in 2015 and recently completed a post-doctoral fellowship in the Neurology department at Oregon Health & Science University focused on understanding the pathophysiology of age-related synucleinopathies like Parkinson disease (PD) and Dementia with Lewy Bodies (DLB).  

In her research, she uses advanced imaging tools and an alpha-synuclein fibril seeding approach to study protein aggregation in a mouse model of PD and DLB. Her lab specializes in merging clinical issues, animal behavior, and exploration of pathology in the cranial sensorimotor system to characterize and treat voice, communication, and swallowing deficits in age-related synucleinopathies.  Allison was president of the Portland-based non-profit Women in Science Portland while she completed her postdoctoral fellowship and is passionate about continuing her work building supportive networks to promote retention and career development opportunities for women in the sciences at Purdue.
