ReMission Foundation, with the support of the Division of Gastroenterology, Department of Medicine at NYU Langone Medical Center led by Mark B. Pochapin MD, is proud to support Peter S. Liang MD, MPH, Instructor at the NYU School of Medicine and an attending physician at the VA New York Harbor Healthcare System and his colorectal cancer prevention research. Dr. Liang studies sociodemographic and geographic disparities in colorectal cancer screening and outcomes, the comparative effectiveness of different screening strategies, and novel methods to increase screening adherence. He also maintains interests in gastric cancer prevention and the management of upper gastrointestinal bleeding.


Dr. Liang is currently planning two database studies of patients who have received care at NYU Langone Medical Center and Bellevue Hospital Center:


  • Risk factors for early onset colorectal cancer

  • Predictors of colorectal cancer screening at Bellevue Hospital Center


The results of these studies will allow us to focus our efforts to increase screening in these communities.


Dr. Liang completed his undergraduate degrees in Biological Sciences and East Asian Studies with honors and distinction at Stanford University and was a Fulbright Fellow in China. He attended Harvard Medical School and earned a master’s in public health in Quantitative Methods at the Harvard School of Public Health. He completed his internal medicine residency at Brigham and Women’s Hospital and his gastroenterology fellowship at the University of Washington. Dr. Liang is actively involved in several national societies, including the American Gastroenterological Association, the American Society for Gastrointestinal Endoscopy, the American College of Gastroenterology, and the National Colorectal Cancer Round Table.
