Zhen Qu

Bio

Zhen uses geospatial analytics to investigate how human activities are altering atmospheric composition and chemistry, and how these changes interact with climate change. She utilizes statistics, high-performance computing and satellite observations to investigate the sources, chemical formation, spatial distributions and trends of air pollutants and greenhouse gases. She develops algorithms and modeling approaches to expand our process-level understanding of man-made and natural emissions. She also applies atmospheric chemistry models to understand the sensitivity of air pollution and its exposure to the emissions of precursor gases.
