Dr. Kenfield is Associate Professor, Epidemiologist, and Behavioral Scientist at the University of California, San Francisco (UCSF). She received her training in Epidemiology from the Harvard T.H. Chan School of Public Health. She received a Prostate Cancer Foundation Young Investigator Award in 2012, was appointed as UCSF Helen Diller Family Chair in Population Science for Urologic Cancer in 2016, and currently serves as Co-Director of Clinical Trials in Urology. Dr. Kenfield has focused her research on nutritional and lifestyle factors and their relationship with cancer development and progression. She has conducted research in large observational cohort studies and led the first study in men with prostate cancer reporting that vigorous activity after diagnosis substantially lowered risk of prostate cancer-specific death, which became part of the US Physical Activity Guidelines for Americans in 2018. Her work focuses on translating scientific findings into behavioral interventions to improve cancer survivorship. She is a principal investigator of multiple randomized trials examining digital health interventions in people diagnosed with cancer. She oversees the first-ever global Phase III trial of exercise in men with metastatic prostate cancer to evaluate the effect of supervised vs. self-directed exercise on overall survival.
