I am a PhD candidate in University of Washington, Seattle.
My advisor is Prof. Becky Alexander in the Department of Atmospheric Sciences. My research in atmospheric chemistry
involves both modeling (GEOS-Chem) and laboratory measurements (oxygen isotopes of sulfate aerosols).
I obtained my bachelor degree in Sun Yat-sen University, China. Motivated by my strong curiosity in oversea education and life,
I attended the master program Meteorology, Physical Oceanography and Climate in Utrecht University, Netherlands.
For my master project, I used GC-IRMS to determine the isotopic signatures of soil production and uptake of H2, under the supervison of
Prof. Thomas Röckmann and Dr. Elena Popa.
My PhD project is about sulfur-halogen interactions in the troposhpere, advised by Prof. Becky Alexander. Our measurements of oxygen-17 excess (Δ17O) of sulfate in the MBL suggest that HOBr/HOCl could be responsible for
30-50% of sulfate formation in the MBL. Inclusion of HOBr+S(IV) reactions in GEOS-Chem reduces tropospheric Bry burden by 50% globally.
The largest uncertainty in tropospheric sulfur-halogen interactions originates from reactive halogen abundances. We need more observations!!!
