Biographical Summary

I work with George Pau and Yaning Liu to develop computationally efficient methods for climate modeling.  One application is quantifying uncertainty in and upscaling coupled hydrology and biogeochemistry in permafrost and peatland ecosystems.

I 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. Please also visit and my personal webpage.

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.
