Dr. Purkayastha’s is an Associate Professor in the Department of Applied Physiology & Health Management. Her research interest is focused on cerebral blood flow regulation and the role of the autonomic nervous system in healthy and diseased humans. She has expertise in transcranial Doppler ultrasonography to examine cerebral blood flow regulation non-invasively. Dr. Purkayastha completed a NIH T32 Postdoctoral Research Fellowship for Translational research in Aging at the Harvard Medical School in Boston, Massachussetts. Dr. Purkayastha obtained her Master’s degree in Physiology from the University of Calcutta, in India and a second Master’s degree in Exercise Physiology at the University of Texas at Arlington. She then graduated with a Ph.D. degree in Biomedical Sciences from the Department of Integrative Physiology at the University of North Texas Health Science Center in Fort Worth.

Dr. Purkayastha’s research studies focus on mild traumatic brain injury, in other words concussion. Despite large numbers of incidences, and the higher risks for long-term health burden, the pathophysiology behind the injury is poorly understood. Dr. Purkayastha’s laboratory examines the link between clinical symptoms such as cognition and postural balance and associated changes in cerebral blood flow regulation. Her goal is to identify objective markers for diagnosis of concussion preventing long-term second-impact syndrome and design appropriate therapeutic intervention in the future.
