Jiajue Chai

Assistant Professor (Research) of Environment and Society


Dr. Jiajue Chai is an atmospheric chemist, with special interests in tracking sources, atmospheric processes and sinks of reactive nitrogen species, and quantitatively understanding their implications for air quality, climate, and human and ecosystem health. To address these questions, his research brings together a novel set of skills including instrumentation, analytical methods, theory and modeling to investigate atmospheric chemistry in both the laboratory and field. His recent work involves characterizing the challenging nitrous acid (HONO) in its sources, sinks and atmospheric chemistry in many ways, to constrain its budget and help predict and mitigate the air quality and climate change.
