I am currently a Research Associate in John A. Paulson School Of Engineering And Applied Sciences, Harvard University, working with Prof. Daniel Jacob. My research are mainly three parts: (1) high-resolution inversion of methane emissions using TROPOMI satellite observations. I have worked on methane emissions over China, the Middle East and North Africa, and am on to the next one! (2) connecting point sources to regional emissions. Recently I am working on using GHGSat and PRISMA point sources to construct a methane emission inventory of Chinese coal mines; and (3) African rice cultivation linked to rising atmospheric methane.
