Dr Chenn is board certified in clinical pathology and molecular genetic pathology. Dr Chenn received his undergraduate degree in biochemical sciences at Harvard University and his MD and PhD in neurosciences from Stanford University. He completed his residency in clinical pathology at the Brigham and Women's Hospital in Boston, Massachusetts, and post-doctoral training in the lab of Dr Christopher Walsh at Beth Israel Deaconess Medical Center in Boston, and was an instructor at Harvard Medical School. Dr Chenn was a faculty member at Northwestern University Feinberg School of Medicine and served as the director of molecular diagnostics at Northwestern Memorial Hospital in Chicago. Most recently, Dr Chenn was a tenured associate professor of pathology at the University of Illinois, Chicago, where his research lab focused on understanding developmental brain disorders and brain cancer. Dr Chenn's laboratory received funding from NIH (NINDS, NCI), Sontag Foundation for Brain Tumor Research, Searle Scholars Program, March of Dimes, Simons Foundation for Autism Research Initiative, and the V Foundation.
Dr Chenn has published over 40 peer-reviewed publications including cover articles in the journals Cell, Science, and Developmental Biology. He formerly served as the director of clinical pathology at the University of Illinois Hospital in Chicago, where he established a new program for Personalized Diagnostics, also known as the Laboratory for Innovative Care and Research. Under his leadership, that program launched several efforts to support patient care decisions, including research to identify genetic variations in cancer that predicted responses to specific therapeutic approaches and the development of clinical diagnostic tests from gene expression signatures.
