Dr. You joined the Medical College of Wisconsin (MCW) as the Joseph F Heil Jr. Professor in Molecular Oncogenesis from Washington University in St. Louis in 2010, where he was the Mary Culver Distinguished Professor of Surgery and director of the chemoprevention program at the Alvin J. Siteman Cancer Center. His research interests are in chemoprevention of lung cancer using a variety of novel agents, identification of candidate lung cancer susceptibility genes by capture-sequencing of targeted regions or genes, identification of frequent somatic mutations in lung adenocarcinomas and squamous cell carcinomas by exome sequencing. He was a member of the Board of Scientific Counselors of the NCI, and was a member of the Chemo/Dietary Prevention Study Section (CDP) and the Chemical Pathology Study Section (CPA) at the NIH. He also served as a member of the NCI’s Cancer Susceptibility Think Tank and Cancer Chemoprevention Think Tank and the chair of the Review Panel for Chemopreventive Agent Development Research Group (CADRG), Division of Cancer Prevention at the NCI. He is an Associate Editor of Cancer Prevention Research and is on the Editorial Board of PLoS One. He served as a member of the editorial boards of Cancer Research and Carcinogenesis. Currently, he serves on the External Scientific Advisory Board for Roswell Park Cancer Institute, an NCI-designated Comprehensive Cancer Center. His publications focus on work in genetics and chemoprevention of lung cancer and his bibliography includes over 230 titles. He have mentored a large number of graduate students and post-doctoral fellows. He received his medical degree in 1982 from Beijing Medical College and his PhD in pathology from the Medical College of Ohio in 1989.
