Assistant Professor of Medicine


Dr. Kristin Bigos is an assistant professor of medicine and of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine. Her research focuses on brain physiology and brain disorders.

Her team currently uses pharmacogenetics and functional neuroimaging to explore novel drug targets and potential therapeutic agents for brain disorders.

Dr. Bigos received her B.S. in premedicine from the Pennsylvania State University. She earned her Ph.D. in clinical pharmaceutical sciences from the University of Pittsburg. She completed a post-doctoral fellowship in the clinical brain disorders branch of the Intramural Research Program of the National Institute of Mental Health under Dr. Daniel Weinberger. 

She is an investigator in the division of clinical pharmacology at the Lieber Institute for Brain Development. She has been recognized with several honors, including a National Institutes of Health Fellows Award for Research Excellence for her research on the functional neuroimaging of glutamate and calcium signaling pathways. more
