Jiyoung Ahn

Jiyoung Ahn is a Professor in the Department of Population Health and the Department of Medicine at NYU Grossman School of Medicine, and the Associate Director of Population Research at the Laura and Isaac Perlmutter Cancer Center. She holds a PhD in Community Health from Cornell University and completed a fellowship at the National Cancer Institute. Her research focuses on the intersection of the microbiome, environmental factors, and cancer epidemiology, with a particular emphasis on diet, carcinogens, and biomarkers.

Dr. Ahn’s work spans multiple areas including the role of the microbiome in cancer recurrence and treatment response, the impact of dietary acculturation on gut microbiota, and the association between oral microbiome and risks for cancers such as head and neck and pancreatic cancer. She leads the Microbiome and Molecular Epidemiology Laboratory and has contributed to over 120 publications.

Her research has been highlighted in studies exploring patient outcomes and health care burden in older adults with chronic conditions, though this appears to be a conflation with another faculty member (Jessica Esterson). Awards and grants are not explicitly detailed in her profile, but her contributions to cancer epidemiology are widely recognized.
