Dr. Trentham-Dietz earned her MS in Statistics and PhD in Epidemiology from the University of Wisconsin-Madison and has been a faculty member in the Department of Population Health Sciences at UW-Madison since 2001. Dr. Trentham-Dietz enjoys supporting pre- and post-doctoral trainees interested in a wide range of issues related to women’s health. Her research focuses on breast cancer prevention, early detection and outcomes. She uses novel and traditional epidemiologic approaches in her studies complemented by methods drawing from health services research and simulation modeling. Dr. Trentham-Dietz conducts research concerning breast cancer prevention and detection by focusing on 1) modifiable lifestyle factors including obesity, physical activity, and environmental exposures to better understand breast cancer etiology and reveal avenues for prevention; 2) ductal carcinoma in situ (DCIS) of the breast which, often detected through mammography, is a non-obligate precursor for invasive breast cancer; and 3) simulation modeling of breast cancer to examine risk-based approaches for improving the balance of benefits and harms of screening.
