Lisa Diamond is a member of the research faculty of the Immigrant Health and Cancer Disparities Service, which facilitates linguistically and culturally sensitive health care services for newcomer populations through research, education, training, program development, policy, and advocacy. Her research focuses on understanding how clinician non-English language proficiency affects the quality of care delivered to patients with limited English proficiency (LEP). Ultimately, she plans to use the results of her research to establish standards for the appropriate use of non-fluent non-English language skills by clinicians and to identify process and outcome measures that capture the quality of cancer care being delivered to LEP patients.
Prior to joining Memorial-Sloan Kettering Cancer Center, Dr. Diamond was a Research Physician and Hospitalist at the Palo Alto Medical Foundation Research Institute. Her research there included a study funded by The California Endowment to identify better methods for measuring clinician non-English language proficiency and determine physician, patient, and system factors that help explain race/ethnic and language-related disparities in care.
Dr. Diamond is a board-certified internist, focusing on inpatient hospital medicine. She completed medical school at the George Washington University School of Medicine and has a Master of Public Health (MPH) degree from the Johns Hopkins Bloomberg School of Public Health. She completed her Internal Medicine residency at New York Presbyterian/Columbia University Medical Center, followed by a fellowship in the Robert Wood Johnson Clinical Scholars Program at Yale University, and a postdoctoral fellowship at the Philip R. Lee Institute for Health Policy Studies at the University of California, San Francisco.
