Pei-an (Betty) Shih, PhD is a Genetic Epidemiologist specializing in the molecular genetic studies of complex traits. She is assistant professor in the Department of Psychiatry, and a faculty member of the Stein Institute for Research on Aging at the University of California, San Diego (UCSD). Dr. Shih serves as Director of Didactic Training for the UCSD Research Fellowship in Biological Psychiatry and Neuroscience Program (T32). She completed a Bachelor of Music degree from University of North Carolina, a Master of Public Management degree from Carnegie Mellon University, and a PhD in Genetic Epidemiology from the University of Pittsburgh. For her postgraduate training, Dr. Shih received a National Kidney Foundation Fellowship Award to study molecular mechanisms underlying genes associated with hypertension and metabolic syndrome risk in population-based samples. Dr. Shih currently holds a National Institute of Health (NIDDK) Mentored Research Scientist Development Award to conduct genetic and lipidomics research in patients with mental illnesses. A component of this work focuses on biomarker and epidemiological studies of cardiometabolic risks and aging parameters associated with atypical antipsychotic use. Another component, and her primary research focus, utilizes a translational "OMICS" strategy to study the genetic and diet interactions underlying the pathogenesis of eating disorders. Dr. Shih’s research interests are psychiatric genetics, pharmacogenetics, the interplay of genes and environment in the causation and progression of mental illness, and the combined use of clinical assessment and biomarkers to personalize interventions and treatments.
