Kim Seungsup graduated from Yonsei University’s School of Medicine, received a master’s degree and a doctorate from the Graduate Schools of Public Health at Seoul National University and Harvard University, respectively. He has worked at the George Washington University’s Graduate School of Public Health and in the Department of Health Policy and Management at Korea University’s School of Health Sciences, and has been an associate professor in the Department of Environmental Health at Seoul National University’s Graduate School of Public Health since 2022.

Using medicine and epidemiology, he researches how social factors such as experiences of discrimination and job insecurity harm the health of socially disadvantaged people such as the disabled, sexual minorities, and non-regular workers. He believes that preventing people from getting sick is as important as treating patients, and he thinks it is society’s responsibility if ordinary people who work hard feel unable to take pride in their lives.
