IVY F. TSO, Ph.D., L.P.

Lab Director

Dr. Tso is interested in understanding the psychological and neural basis of altered social and emotional processes in psychiatric disorders, especially schizophrenia, bipolar disorder, and related syndromes. She uses behavioral experiments, electrophysiology (EEG/ERP), neuroimaging (fMRI), eye tracking, and neuromodulation (TMS) methods to identify biobehavioral markers and to delineate dynamic brain network models underlying these disorders. The ultimate goal of her research is to develop effective and personalized treatments to help people with severe mental illnesses to lead a meaningful and fulfilling life.

Dr. Tso is a licensed clinical psychologist and serves as the Training and Clinical Director of the Program for Risk Evaluation and Prevention (PREP), a clinical and research program for youth with early signs of psychosis and serious mental illnesses. She is actively involved in patient care, clinical training, and community educational outreach.

Dr. Tso is an Associate Professor of Psychiatry, Medical School, and Adjunct Associate Professor in Psychology, LSA, at the University of Michigan. She received her B.Soc.Sc. (Psychology) and M.Phil. (Psychiatry) from the University of Hong Kong. She completed her Ph.D. in Clinical Psychology and postdoctoral training at the University of Michigan.
