Between 2002 and 2006, she pursued a doctoral degree in environmental engineering while working. Since 2006, she has primarily focused on research in precipitation and cloud chemistry, atmospheric aerosols, and the environmental behavior of persistent pollutants. From June to September 2010, she was a visiting scholar at Miami University, learning about the analysis and detection techniques of environmental POPs (Persistent Organic Pollutants), and from March to April 2018, she served as a senior researcher at SUNY Upstate Medical University and SUNY, co-supervising graduate students in conducting toxicity experiments on fine particulate matter and developing and improving atmospheric mercury models. To date, she has supervised 46 graduate students to graduation.
