Steven E. Arnold, M.D., Director

Dr. Arnold is Associate Professor of Psychiatry and Neurology at the University of Pennsylvania. After receiving his M.D. from Boston University, he completed residency training in Psychiatry at the New York State Psychiatric Institiute / Columbia Presbyterian Medical Center in New York and Neurology at the University of Iowa Hospitals and Clinics in Iowa City. He also completed fellowship training in Behavioral Neurology / Cognitive Neuroscience and was a post-doctoral associate in Neuroanatomy in Iowa. Dr. Arnold is board certified in both Psychiatry and Neurology. He is the Director of the Cellular and Molecular Neuropathology Program, Director of the Clinical Neuroscience Track in the School of Medicine, Associate Director of the Mahoney Institute of Neurological Sciences, a Senior Fellow in the University of Pennsylvania's Institute on Aging, and a clinician in the Hospital of the University of Pennsylvania's Memory Disorders Clinic. Dr. Arnold's research focuses on brain pathology in schizophrenia, aging, and neurodegenerative diseases.

Chang-Gyu Hahn, M.D., Ph.D., Associate Director

Dr. Hahn is Assistant Professor of Psychiatry at the University of Pennsylvania. Dr. Hahn received his M.D. at Seoul National University in Seoul, Korea and his Ph.D. in Neurobiology at the University of Connecticut in Storrs, where his work focused on activity dependent gene regulation of cell adhesion molecules. He then completed his residency in Psychiatry and a research fellowship in Neuropsychopharmacolgy, both at the University of Pennsylvania. Board-certified in Psychiatry, Dr, Hahn was an Instructor and Assistant Professor at Allegheny University/ MCP-Hahnemann University before returning to the University of Pennsylvania as Assistant Professor. Dr. Hahn's laboratory research focuses on calcium signaling and gene expression in bipolar disorder, while his clinical research activities include psychopharmacological management of bipolar disorder as a clinician in the Bipolar Disorders Unit at the University of Pennsylvania.

Lise Rioux, Ph.D.

Dr. Rioux is Research Assistant Professor at the University of Pennsylvania. Dr. Rioux received her Ph.D. in Neurobiology at the University of Laval, Quebec, Canada where her thesis work was on the pharmacological and behavioral effects of dopamine neuron transplants in rodent lesion models of Parkinson’s disease. This was followed by post-doctoral work at the University of Pennsylvania in receptor pharmacology and signal transduction pathways in the Departments of Psychiatry and Pharmacology. Dr. Rioux’s main interests are in retinoid signaling and the molecular neuroanatomical aspects of development and plasticity in schizophrenia.
