Jiyoung Ahn, PhD, RD

Principal Investigator
Associate Professor of Population Health
Associate Director, Perlmutter Cancer Center

Dr. Ahn has more than 15 years of experience in designing and carrying out epidemiologic investigations on cancer, including the successful execution of case-control and cohort studies in national and international settings. Her research on the etiology of cancer has involved investigations of diet, anthropometric factors, genetics and, most recently, the human microbiome. Currently, Dr. Ahn is PI of multiple NCI-funded studies of diet, human microbiome and gastrointestinal cancers. She has published more than 90 peer-reviewed papers (including first/senior authored in Nature Genetics, JNCI, JAMA Internal Medicine, and Cancer Research). As Associate Director of Population Sciences in the NYU Perlmutter Cancer Center, she provides strategic leadership in population science research and implementation. She received her PhD from Cornell University, and completed a post-doctoral fellowship at the National Cancer Institute.
