CTSI Profile

Overview

Dr. Petzinger is a board certified neurologist specializing in the care of patients with Parkinson’s disease. She divides her time between clinical care of patients and laboratory research. The primary focus of Dr. Petzinger’s research is to better understand how to promote brain repair following injury and to translate these findings into new therapeutic treatments. Dr. Petzinger has been involved in numerous federally funded research grants. Currently, she is the principal investigator on the US Army Research Grant entitled Behaviorial and Pharmacolgical Enhancement of Neuroplasticity in Basal Ganglia of the MPTP-Lesioned Mouse and Non-Human Primate.
