Joseph Su, Ph.D., M.P.H., is a Professor of Epidemiology and Associate Dean for Academic Affairs at the Peter O’Donnell Jr. School of Public Health. He is also a co-director of the Simmons Comprehensive Cancer Center Office of Training and Education. He received his Ph.D. in Nutritional Epidemiology at the University of North Carolina at Chapel Hill and his M.P.H. in Public Health Nutrition at the University of Minnesota, Minneapolis. He had his undergraduate training in Nutritional Sciences at the University of Minnesota, St. Paul, and in Chemistry at Chung-Yuan University in Taiwan.

 

Dr. Su has spanned his career at both academic medical centers and public services at the federal Government. Previously, he served as a Branch Chief at the Division of Epidemiologic Research of the Center for Medical Devices and Radiological Health, where he oversaw all post-approval Class III cardiovascular and neurological devices and in-vitro diagnostic devices in the U.S. market. Prior to the FDA, he was a Program Director at the Epidemiology and Genomic Research Program, Division of Cancer Control and Population Sciences, National Cancer Institute (NCI), where he managed a diverse grant portfolio on cancer epidemiologic studies that involved nutrition, environmental exposure, genetics/ epigenetics, application of -omics in population-based studies, and quality of life and survival after cancer diagnosis.

 

Dr. Su is a cancer epidemiologist by training, specializing in assessments of nutritional and environmental exposure and their interaction with genes that are associated with cancer development and progression. He is also experienced in minority recruitment and follow-up, optical character recognition (OCR) data processing and validation, and survey study design. Additionally, his analytical chemistry laboratory is equipped and experienced in human biological sample processing, shipping, and storage. Dr. Su has been involved in population-based studies on genomics, epigenomics, and metabolomics research. His laboratory is equipped with a state-of-the-art ICP-MS and an HPLC system. He welcomes collaboration to examine the association between diet, heavy metal exposure, and adverse health outcomes.
