Joey Trampush

Dr. Trampush is an Assistant Professor of Psychiatry and the Behavioral Sciences at the Keck School of Medicine at USC. He is a developmental neuropsychologist and geneticist. His research program examines psychopathology across the lifespan, with a particular focus in three core areas: 1) molecular genetics of neurocognitive function in health and disease; 2) neurocognitive function in psychiatric illness; and 3) neurocognitive development and individual trajectories. This work aims to enhance our understanding of the biological and genetic basis of severe psychiatric illnesses that emerge early in life, are chronic across the lifespan, and among the leading causes of disability worldwide.
