  • Assistant Professor of Medicine


Dr. Kristin Bigos is an Assistant Professor of Medicine, Psychiatry, and Pharmacology at the Johns Hopkins University School of Medicine. Her research focuses on neuropsychiatric drug development and a precision medicine approach to the treatment of mental illness.

The Bigos Lab uses functional MRI as a biomarker to test the neural effects of drugs designed to treat symptoms of mental illness.  Her lab currently has a pharmacoMRI study to develop a treatment for cognitive dysfunction in schizophrenia. Other studies aim to identify patient-specific variables including sex, race, and genetics that impact drug clearance and clinical response to better select and dose antipsychotics and antidepressants. 

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 Pittsburgh. 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. Before joining Johns Hopkins, she worked as an Investigator at the Lieber Institute for Brain Development. more

Research Summary

The Bigos Lab focuses on a Precision Medicine approach to the treatment of psychiatric illness. In addition, this lab employs functional neuroimaging and genetics as biomarkers in neuropsychiatric drug development. A recent study used functional MRI to test the neural effects of a drug with the potential to treat cognitive dysfunction in schizophrenia. Other studies aim to identify patient-specific variables including sex, race, and genetics that impact drug clearance and clinical response to better select and dose antipsychotics and antidepressants.
