Research/Clinical Interests

Dr. Lee-may Chen is board certified in gynecologic oncology. Her clinical focus and research centers on the systematic identification and management of individuals who are at a high risk of developing gynecologic cancer. Even before PARP inhibitors were identified to target homologous recombination deficiency in ovarian cancer, Dr. Chen has been championing genetic testing for all at risk populations, including patients with ovarian and endometrial cancer. Her research projects involving hereditary gynecologic cancer risk and treatment have been published in The New England Journal of Medicine, Journal of Clinical Oncology and Obstetrics and Gynecology, among other influential medical journals.

She is a passionate educator, and highly involved in the academic development and training of fellows, residents and medical students at UCSF. She was elected to the UCSF Haile T. Debas Academy of Medical Educators in 2008.

Since 2015, Dr Chen has served as Division Director, and is active in the UCSF ERAS Pathway Working Group, Gyn Perioperative Governance, Medical Center Credentialling, and the Cancer Center Quality Council, representing the Cancer Committee, which she serves as Chair. Dr. Chen represents UCSF on the NCCN Guideline panels for ovarian cancer as well as the genetic/familial high risk. Recently, Dr. Chen has also been appointed as the 2022-2024 SGO Liason to the ACOG Board of Directors.

Dr. Chen also speaks Mandarin Chinese.
