Research Interests

Modeling and Observing Atmospheric Carbon

Earth Science: Carbon Cycle

Quantification of methane and carbon dioxide emissions using a variety of observing platforms (e.g. towers, aircrafts, and satellites) and corresponding models (e.g. NASA GEOS). I am interested in understanding uncertainties in methodologies such as inverse modeling and related statistical optimization techniques.

Modeling and Analysis of Air Quality

Earth Science: Ozone

Air quality prediction (particularly surface ozone) with statistical models, effects of meteorology on surface ozone, interpretation of probabilistic air quality forecasts.
