Dr. Susser's primary research has been on the epidemiology of mental disorders, and on examining the role of early life experience in health and disease throughout the life course. His international collaborative birth cohort research program (The Imprints Center) seeks to uncover the developmental origins of psychiatric and neurodevelopmental disorders such as schizophrenia, autism and ADHD, as well as other complex diseases. Among the risk factors explored are prenatal exposures to infectious disease and toxic chemicals, childhood nutrition and environment, and genetics, as well as the interplay of genetic and environmental risk factors. His most recent research addresses the role of in utero de novo genetic mutations in the development of schizophrenia in adulthood. Dr. Susser’s work has addressed the health of inner city populations, examining relationships between homelessness, mental illness, and HIV/AIDS.
