Biography
Dr. Ma is Professor of Epidemiology at the Yale School of Public Health, and Co-Leader of the Cancer Prevention and Control Research Program at the Yale Comprehensive Cancer Center, Yale School of Medicine. She studies the etiology and health outcomes of different types of cancer, with a focus on pediatric cancer and malignancies of the hematopoietic system (e.g., leukemia, lymphoma, myelodysplastic syndromes, and myeloproliferative neoplasms). Her research has addressed the impact of immunological factors, chemical exposures, and genetic characteristics on the risk of cancer. In addition, she has assessed the patterns of care and cost implications of cancer screening and treatment in older adults.
