I have begun a Postdoctoral Fellowship at the Lawrence Berkeley National Laboratory; see my webpage there: I recently completed a Postdoctoral Fellowship at the Princeton Environmental Institute, working with Prof. Steve Pacala and Dr. Elena Shevliakova. I was working with Dr. Benjamin Sulman to improve the treatment of soil carbon cycling and subgrid horizontal heterogeneity in the land-surface component of the GFDL earth system model, with application to understanding interactions between peatlands and climate change.

I completed a Ph.D. in UC Berkeley's Energy and Resources Group, working with Dr. William Riley, Prof. Margaret Torn, Prof. William Collins, and Dr. Charles Koven in the Climate Sciences Department at the Lawrence Berkeley National Lab. The dissertation is available upon email request. I am affiliated with the IMPACTS project and the CESM Land Model Working Group. During my Ph.D., I used land-surface modeling to better understand feedbacks to climate change. I developed a coupling between WRF and CLM in order to study the effects of land cover change in California. I also developed an improved lake model for CLM (Subin et al., 2012a; Subin et al., 2012b) and helped develop a global terrestrial methane emissions model with Dr. Riley. My previous work at Berkeley included work on wind energy economics and the options for greenhouse gas emissions reduction in California's transportation sector.

Research Interests: Interactions between changes in terrestrial surface and subsurface physical and biochemical properties and changes in regional and global climate: regional and global climate modeling; land cover and land use change; lake physics and dynamics; wetland and methane biogeochemistry; permafrost and thermokarst physics; feedbacks to climate change.

Personal interests include science, politics, beer, bicycling / outdoors, and cats.
