My research interests are in mathematical and computational models of flow and transport and phase change in Earth science models for energy and environmental applications. In particular, I have been studying methane transport in porous media involving phase transitions at large time scales for basin modeling and in response to climate change. Methane gas is a greenhouse gas, but also a potential energy resource. My results include rigorous numerical stability results of numerical models for equilibrium and non-equilibrium cases. Current work involves modeling of permafrost thawing followed by the destabilization of methane hydrate deposits beneath the permafrost-bearing sediments, which results in methane gas release into the environment. We are also looking at pore-scale models of the mass and energy flow and upscaling to Darcy scale.

Non-Work Related Activities/Interests:

I am interested in helping students who struggle with math in school. In particular, I helped middle school and high school students whose second language is English by teaching math, chemistry, and physics via in-person and online tutoring.
