Research Programs:

I am focused on studying the air quality issues, including transport, transformation and fate of pollutants, such as reactive nitrogen. My research interests include measurement and modeling of surface-atmosphere exchange of trace gas and particles in agricultural, forest, coastal and urban ecosystems. I use datasets derived from measurement campaigns for input and validation of computer models results. The goal of my research is to refine the estimation of air pollution and assess the risks to human health and the environment.


In recognition of the air pollution issues in urban areas, my research also focuses on optimizing the use of existing federal data to improve the prediction of hazardous material dispersion in urban environments. In this context, the DCNet data provide a unique opportunity for real-time meteorological observations over the greater National Capital Region (NCR) to support development of numerical weather prediction models as well as provide the meteorological observations to initialize dispersion models on which critical decisions for emergency response are based. The DCNet network was established and operated by NOAA/ARL in 2003 to collect a large data base of meteorological measurements in Washington, D.C. NOAA ARL is currently working on expanding and upgrading the DCNet network in the NCR.


I’m currently involved in the Atmospheric Emissions and Reactions Observed from Megacities to Marine Area (AEROMMA) campaign ( to conduct ground-based and mobile atmospheric NH3 concentration measurements in 2023. The ground-based NH3 measurements will take place at the Yale Coastal Field Station (YCFS) to study the seasonal variability of NH3 concentrations over a coastal ecosystem. The mobile NH3 measurements will be performed at the YCFS and in NYC to better understand the spatial and temporal NH3 variations in urban and suburban areas.
