Ronald Garcia M.D., Ph.D. (Senior Mentor - TWIN 2)
Assistant Professor of Psychiatry, Harvard Medical School
Program Director of Neuromodulation Therapeutics, Clinical Neuroscience Laboratory of Sex Differences in the Brain (Goldstein Lab)
Martinos Center for Biomedical Imaging, Massachusetts General Hospital
Dr. Ronald Garcia is an Instructor at the Department of Psychiatry at Massachusetts General Hospital and Harvard Medical School. His main research interests include the study of pathophysiological mechanisms underlying the comorbidity of major depression and cardiovascular disease as well as the development and translation of novel technologies that can be used for modulation of brain circuitry responsible for mood/anxiety and cardiovascular dysregulation in depressed individuals.
Dr. Garcia received a M.D. degree from Universidad Industrial de Santander, Colombia, and a Ph.D. degree in neuroscience from Universidade de Brasilia, Brazil. Before joining Massachusetts General Hospital, Dr. Garcia was Research Director at the Cardiovascular Foundation of Colombia (2010-2012) and conducted research and published extensively on cardiac autonomic dysregulation and vascular dysfunction in patients with hypertension-related conditions, mood disorders and cardio- and cerebro-vascular diseases. Since 2012, Dr. Garcia is based in the US, where he has been involved in the development of functional neuroimaging studies aimed to identify central mechanisms of cardiac and vascular regulation.
In addition, in collaboration with Dr. Jill Goldstein at the Clinical Neuroscience Laboratory of Sex Differences in the Brain and Dr. Vitaly Napadow at the Martinos Center for Biomedical Imaging, Dr. Garcia’s research has been oriented to the evaluation and optimization of non-invasive vagus nerve stimulation as a potential neuromodulatory intervention for sex-dependent alterations in the brain circuitry controlling mood and autonomic tone in major depression. His long-term research interests include the development and clinical translation of this and other non-invasive neuromodulation tools for the treatment of psychiatric disorders and their comorbidity with cardiovascular disease.
