Catherine Mezzacappa, MD, MPH


I am a fellow in the Division of Digestive Diseases. My research is focused on better understanding the relationship between metabolic disease (diabetes, steatotic liver disease), progression of liver fibrosis, and hepatocellular carcinoma for the purposes of improving clinical risk stratification. I am also interested in gene-environment interactions and how they influence the implementation science of screening for gastrointestinal cancers. Prior to beginning a career in medicine, I completed a Master’s in Public Health (MPH) with a concentration in Epidemiology at Boston University School of Public Health, at which time I was awarded the Dr. Theodore Colton Prize for Excellence in Epidemiology. I then worked in health system program monitoring and evaluation for several international health non-governmental organizations prior to attending medical school at the University of Pennsylvania and then joining the Internal Medicine residency at Yale New Haven Hospital.
