Abstract I’m Guangjie Zheng, a postdoc in Washington University in St. Louis. I’m seeking for academic faculty position in the field of atmospheric science/aerosols.
During my Ph.D. studies in Tsinghua University, China, I've been studying the extreme Beijing air pollutions. Major results include: (1) the severe winter haze was driven by stable synoptic meteorological conditions, and not by an abrupt increase in emissions; (2) secondary species, especially sulfates, were the major constituents of PM2.5 during this period, and (3) atmospheric chemistry during extreme hazes is characterized by weakened photochemistry versus enhanced heterogenous reactions. Subsequently, together with my collaborators in Max-Planck Institute for Chemistry in Germany, we proposed the reactive nitrogen chemistry in aerosol water as the major sulfate formation pathway during the extreme hazes. These findings generated 5 first-author peer-reviewed papers, including 2 ESI Hot Paper (0.1%), one of which published in Science Advances.
After my Ph.D. graduation in 2016, I joined Dr. Jian Wang’s group at Brookhaven National Laboratory, and moved to current affiliation with the group in 2018. During the postdoc, I’ve been focusing on the aerosol properties and processes in remote marine environment, based on the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) campaign and long-term observations at the ENA site. Some of the on-going topics include: (1) key processes that drive the population of cloud condensation nuclei in remote marine boundary layer, (2) property evolutions of Canadian wildfire aerosols during the long-range transport, (3) new particle formation in remote marine environment, and (4) determining factors of size-resolved aerosol hygroscopicity in ENA.
My contract will end in Sept. 2020, and early termination is possible if needed. Please contact me through: Cell phone: 646-301-2369 Email: gzheng@wustl.edu / guangjie.zheng@gmail.com
