Juliet Lumati, MD, MPH FACS FSSO is a Hepatopancreatobiliary and Gastrointestinal Surgical Oncologist at Northwestern Medicine and a Clinical Assistant Professor at Northwestern University Feinberg School of Medicine. She is affiliated with the Robert H. Lurie Comprehensive Cancer Center of Northwestern University, the Institute for Public Health and Medicine, and the Robert Havey Institute for Global Health. She is the Principal Investigator of COST-FIN, the first pragmatic randomized controlled trial in Sub-Saharan Africa evaluating the impact of a financial navigation intervention for cancer patients, designed to reduce financial toxicity, treatment abandonment, and catastrophic health expenditures.
Dr. Lumati’s research focuses on health services and implementation science within global oncology, with a particular emphasis on healthcare financing and access to cancer care in Sub-Saharan Africa. She earned her medical degree from the University of California San Diego School of Medicine through the Program in Medical Education–Health Equity and completed a Master of Public Health in Health Policy and Management at the Harvard T.H.

She is an alumna of the UC-GLOCAL Fogarty Fellowship (UCGHI Consortium, 2017–2018), during which she conducted research in Ghana evaluating the impact of the National Health Insurance Scheme on out-of-pocket payments for surgical care. Over the past five years, she has also served as a part-time surgical oncology consultant at Lakeshore Cancer Center in Lagos, Nigeria.
Dr. Lumati is a commissioner for the Lancet Commission on Non-Communicable Diseases and Poverty (Ghana) and serves as a peer reviewer for multiple global health journals. She has received numerous honors, including the ASCO Young Investigator Award in Global Oncology and the Department of Surgery Research Mentor of the Year Award (2025), as well as recognition on the National Dean’s List, San Diego Top 25 in Their 20s, and awards for leadership and excellence in international student life.
Her long-term goal is to improve access to high-quality cancer care in Sub-Saharan Africa by strengthening multidisciplinary oncology care—particularly surgical services—through sustainable healthcare financing, pragmatic trial design, and policy-relevant implementation science
