Kelli A. Duncan

Associate Professor of Biology

My research lab (including undergraduate researchers) examines the role of steroid hormones on repair of the nervous system following traumatic brain injury (TBI).  Specifically, we study how these steroids mediate inflammation following TBI. I received my PhD in Biology from Georgia State University in 2008, where I studied sex differences in neuronal development. I then continued this research as a post-doc at Lehigh University where I also began to examine the role of steroid hormones following TBI, until starting my own lab here at Vassar College in 2011.
