My research goal is to improve the understanding of the processes determining the distribution of reactive gases and aerosols, and their implications for air quality, public health, and climate.
My research program combines remote sensing, modeling, and data assimilation techniques.
- Atmospheric chemistry and its implications
- Monitoring of trace gases from space
- Modeling of atmospheric composition
Current Research and Projects:
- Tropospheric halogen chemistry
- Retrievals of HCHO from OMPS satellites
- Validation of satellite trace gas retrievals
- Effect of sea-salt aerosol on tropospheric bromine chemistry (Paper submitted to ACP)
- Long term trend in HCHO columns over the North America and its driving factors (Paper published on GRL)
- Surface HCHO concentrations retrieved from satellites and the heath impacts (Paper published on ES&T; Media Coverage; Covered by PNAS Front Matter)
- Validation of HCHO retrievals using SEAC4RS aircraft observations (Paper published on ACP)
- Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS): GEOS-Chem Team (NASA Group Achievement Award)
- Anthropogenic emissions of highly reactive VOCs inferred from oversampling of HCHO columns: Implications for Oil/Gas operations and Urban point sources (Paper published on ERL; Media Coverage)
