Panagiotis Roussos, MD, PhD

Dr. Roussos is a Professor of Psychiatry and Genetics and Genomic Sciences, and the Director of the Center for Disease Neurogenomics at the Icahn School of Medicine at Mount Sinai. He received his medical and doctorate degrees from the University of Crete in Greece and he completed his residency in Psychiatry (research track) at Icahn School of Medicine at Mount Sinai followed by a MIRECC research fellowship in schizophrenia. His early research focused on the genetic exploration of intermediate cognitive phenotypes, including the prepulse inhibition of the startle reflex in human subjects and restoration of deficits using a pharmacogenomic approach. During his residency in psychiatry (Physician-Scientist Research Track) at Icahn School of Medicine at Mount Sinai, he worked on human postmortem studies by integrating genomics with gene expression and gene network approaches

Dr. Roussos's research focuses on the integration of high-dimensional data, such as genomic, epigenomic and transcriptomic, using advanced biostatistical methods in order to identify some of the mechanisms through which risk genetic variants increase the risk for neuropsychiatric diseases. He applies a combination of molecular biology and bioinformatics approaches to tackle these questions.
