Jia Coco Liu, Ph.D.

Hello! Thanks for visiting my site. Recently (as of June 2019) I took a new job in a completely different industry, just to explore something I've never tried before. Wish me luck ;) Your interest in my past research is still appreciated!

Before June 2019, I was an environmental epidemiologist in the field of air pollution and human health. ​I worked as an Epidemiologist (Scientist III) at the Electric Power Research Institute (EPRI) in Palo Alto, California. Prior to EPRI, I was a postdoctoral fellow with Dr. Roger Peng at the Department of Biostatistics, Johns Hopkins Bloomberg School of Public Health. My postdoctoral research developed new methods to advance the understanding of the exposure and health impact of ambient air pollutant mixtures. I earned Ph.D. from Yale University (2016) advised by Dr. Michelle Bell, and B.A. from Middlebury College (2011).

My papers can be found on my Google scholar page.

My dissertation work has been cited by news media such as the Washington post and New York Times.

  • Air pollutant mixtures and health
