Biography
Yiqun Ma is a doctoral student in the Department of Environmental Health Sciences at Yale School of Public Health. She is interested in the intersection of climate change, air pollution, and human health, such as heat-related cause-specific mortality and the effects of air pollution on mental health. She also hopes to learn more about the exposure assessment of air pollution and air temperature. Yiqun holds a Bachelor of Management Sciences from Zhejiang University, China.
