David A. Drew, PhD - Director of the Biobanking

Dr. David A. Drew is the Director of Biobanking in the CTEU and Assistant Professor of Medicine and Gastroenterology at MGH and HMS.

His long-term research has focused on the interception and prevention of gastrointestinal disorders, primarily gastrointestinal cancers, through chemoprevention, lifestyle modification, or enhanced endoscopic screening methods. Recently, this interest has been focused on the molecular mechanisms, particularly those influenced by the gut microbiome, driving gastrointestinal disease and cancer, and the mechanisms by which pharmacologic agents, such as aspirin, prevent the development of GI disorders. Broadly, his training has provided him a strong foundation in basic and translational research, the gut microbiome, colorectal carcinogenesis, precision prevention, epidemiology/biostatistics, and cancer genetics. As the Director of Biobanking for the CTEU, he seeks to build robust biospecimen repositories that are paired with high-resolution metadata to build truly translational platforms derived from clinical research studies. In response to the COVID-19 pandemic, he helped lead the COVID Symptom Study’s implementation in the U.S. and establish the Coronavirus Pandemic Epidemiology (COPE) consortium. He is a member of the Stand Up To Cancer (SU2C) Gastric Cancer Interception Team, the SU2C Colorectal Cancer Healthy Equity Dream Team, and is independently funded by the National Institutes of Health, National Cancer Institute, National Institute of Diabetes and Digestive and Kidney Disorders, and the American Gastroenterological Association.


Dr. Drew earned a PhD in Biomedical Science from the University of Connecticut and also holds a B.S. in Biochemistry/Biophysics from Rensselaer Polytechnic Institute.
