Cristina A. Fernandez, Ph.D., MS.Ed., is a psychiatric epidemiologist at Harvard T.H. Chan School of Public Health. She also holds academic appointments at the Miami VA Healthcare System, the University of Miami Miller School of Medicine, and serves as a Statistical Editorial Advisory Board Member for the Journal of Traumatic Stress (published by the International Society for Traumatic Stress Studies, the lead organization for research on traumatic stress and PTSD). She has a broad multidisciplinary training in epidemiology, biostatistics, clinical psychology, psychoneuroimmunology, and cultural psychiatry. She also has extensive experience providing mental health services (i.e., Cognitive Behavioral Therapy) in medically underserved communities, particularly among homeless populations. Her current research examines: 1) the psychiatric effects of mass disasters in Latin America; 2) identifying the causes of PTSD at multiple levels – from describing the social patterning of trauma exposure to examining the molecular mechanisms via which adverse environments get “under the skin” and cause disease; 3) uncovering novel and improved treatments for PTSD; and 4) reducing mental health disparities and stigma, particularly among racial and ethnic minorities.
