I am currently a postdoctoral associate working with Arlene Fiore in the Earth, Atmospheric, and Planetary Sciences Department at the Massachusetts Institute of Technology. I received my Ph.D. working with Randall Martin in the Environmental, Energy, and Chemical Engineering Department at Washington University in St. Louis.

My current work focuses on using multiple sources of data, including satellite retrievals, ground-based observations, and model simulations to investigate air pollution, and inform the uncertainties in air quality assessments. My doctoral research focuses on using data-driven methods combined with the air quality model, ground-based observations, and satellite retrievals to investigate air pollution. I have been working on estimating of fine resolution global $\rm{PM_{2.5}}$ concentration, developing regional $\rm{PM_{2.5}}$ and composition concentration with uncertainties.

Prior to my PhD, I received a B.S. in Physics and a B.A. in Economics from Peking University in 2020. My undergraduate research was advised by Dr. Lin Zhang focuses on analyses of fine particulate matter sources across China with an adjoint version of the GEOS-Chem model and investigation of diurnal ammonium trends in Beijing with a nested GEOS-Chem model.

In my spare time, I like hiking, pickleball, and cooking.
