I am interested in understanding the genetic regulatory determinants of drug response through the study of chromatin, the complex of DNA and protein in the cell nucleus. My lab uses the tools of epigenomics and functional genomics to understand how epigenetic variation influences drug response and, in turn, how drugs and toxins may affect the epigenome. For example, we are currently funded by the National Institute on Aging to study how epigenetic changes in normal aging affect rates of drug metabolism. We collaborate with colleagues in the VCU School of Medicine to study epigenetic mechanisms of response to central nervous system (CNS) drugs, in addition to epigenetic effects of toxins such as organophosphate. Finally, we have received several grants to study brain transcription factors. We have started to evaluate the possibility of drugging these factors and their wider regulatory networks as a means to treat CNS disorders. Please feel free to contact me about potential research openings in my lab, including undergraduate and PharmD internships/electives, PharmD summer fellowships, graduate student and postdoctoral positions.
