Carlos A. Zarate, M.D.

Experimental Therapeutics and Pathophysiology Branch
10 Center Drive, CRC
Bethesda MD 20892-

Dr. Zarate earned his medical degree from the Catholic University of Cordoba in Argentina. He completed a clinical psychopharmacology fellowship at McLean Hospital in 1993, after which he remained on staff until 1998. In 1998, Dr. Zarate joined the faculty at the University of Massachusetts Medical School. In 2001, Dr. Zarate joined the Mood and Anxiety Disorders program at the NIMH and, in 2009, formed the Experimental Therapeutics and Pathophysiology Branch.

His achievements and awards include the Ethel-DuPont Warren Award and Livingston Awards, Consolidated Department of Psychiatry, Harvard Medical School; Outstanding Psychiatrist Research Award, Massachusetts Psychiatric Association; Program for Minority Research Training in Psychiatry, APA; the National Alliance for Research on Schizophrenia and Depression Young Investigator Award; National Alliance for Research on Schizophrenia and Depression Independent Investigator Award; the National Institutes of Health Director’s Award Scientific/Medical, the 2011 Brain & Behavior Research Foundation Award for Bipolar Mood Disorder Research, the 2013 National Institute of Health Director’s Award—Scientific/Medical Achievement and Mogens Schou Research Award: Bipolar Disorder and the Simon-Bolivar Award American Psychiatric Association; 2015 Ruth L. Kirschtein Mentoring Award NIH and the Astute Clinician Lecture Award, NIH.

Dr. Zarate’s research focuses on the development of novel medications for treatment-resistant depression and bipolar disorder. His branch conducts proof-of-concept studies utilizing novel compounds and biomarkers to identify potentially relevant drug targets and biosignatures of treatment response.

The Experimental Therapeutics & Pathophysiology Branch (ETPB) has been dedicated to developing and implementing novel, and much-needed, treatments for mood disorders. The ETPB research focuses on developing innovative and ground-breaking therapeutics for treatment resistant depression and bipolar disorder, identifying biomarkers that predict treatment response, and understanding the neurobiology of treatment response in patients with severe, recurrent mood disorders. The research program is truly translational in nature. The ETPB conducts proof-of-concept studies using novel compounds and biomarkers (magnetoencephalography [MEG] and polysomnography [PSG], positron emission tomography [PET], functional magnetic resonance imaging [fMRI] and magnetic resonance spectroscopy [MRS]) to identify potentially relevant drug targets and biosignatures of treatment response. The Branch’s long-term goal is to develop the next generation of antidepressant agents, thereby significantly improving the treatment of severe treatment-resistant depression. In addition, the Branch provides thoughtful, supportive training to develop the next generation of clinical translational researchers.
