Imaging Brain Chemistry in Psychosis and Patients at Clinical High Risk for Psychosis

My goal is to develop a better understanding of how the brain functions in-vivo. Specifically, my focus is the pathophysiology of the early course of schizophrenia and its treatment. In pursuit of this goal I use phenomenology and positron emission tomography (PET).
