Methane Mitigation 

Methane is the second most important greenhouse gas after CO2. I use an Earth system model and machine learning to study its atmospheric lifetime, the lifetime feedbacks, and what they mean for the climate benefits of mitigation.

 Atmospheric Chemistry Modeling

Ground-level ozone is a harmful secondary air pollutant. It formsunder sunlight and  builds up over urban areas in hot weather. I use the WRF-Chem model to simulate how ozone are produced and transported through the troposphere.

 Cloud Feedback

Cloud feedback and aerosol-cloud interactions are major sources of uncertainty in Earth system models. I use CESM2 and E3SMv2 to analyze the correlation between the two and the physical processes that link them.
