Her research program is focused on identifying the causes of breast cancer and prostate cancer, with a special interest in the role of potentially modifiable lifestyle factors (physical activity, obesity, vitamin D, dietary factors), early life exposures, and genetic susceptibility. Many of her research studies are focused on Latina and African American populations and investigate racial/ethnic differences in risk factors and their contribution to cancer disparities.

Dr. Theresa Keegan, Co-Principal Investigator
Dr. Keegan received her PhD in Epidemiology from Stanford University in 2003, after receiving her MS in Wellness Management from Ball State University in 1999.
Dr. Keegan is particularly interested in modifiable factors and health behaviors that influence the occurrence of cancer and survival after cancer, and was funded to assess the relationship of life-time body size and physical activity to risk of Hodgkin lymphoma, and to assess the impact of the neighborhood built environment on the risk of breast cancer and survival after breast cancer. Dr. Keegan’s research also focuses on cancer surveillance, cancer outcomes and cancer survivorship, particularly among adolescents and young adults 15 to 39 years of age. She has worked extensively with population-based cancer registry data to understand patterns of cancer incidence, treatment and survival, and been involved with multiple studies examining patient experiences with cancer and patient-reported outcomes after cancer diagnosis.
Dr. Keegan is an Associate Professor in the Division of Hematology and Oncology at the University of California (UC) Davis School of Medicine and a member of the UC Davis Comprehensive Cancer Center.
Judy Goldstein, Project Manager

Prior to her career in public health, Judy worked in policy and social science research in the area of program evaluation. Judy has a Bachelor’s Degree from the University of California at Berkeley and has a Cancer Data Systems Certificate from UCSF. She finds the LEGACY Girls Study one of the most satisfying and interesting projects she has ever worked on because the study focuses on health as well as psychosocial aspects of everyday life that affect girls today. Judy would love to meet every LEGACY girl and mom in the study to learn and record their reasons for joining and continuing to participate in this very important study.
