Prospective Students

I anticipate accepting one new graduate student for the 2013-2014 year. If you are interested in my research group to pursue Ph.D. research, please feel free to contact me.  I am seeking graduate student to work on one of the following projects: (1) Investigating the interactions between biogeophysical and biogeochemical processes in the northern high latitudes using an earth system model (ESM). In particular, this project aims at improving our understanding how the Earth’s climate, biogeochemical and biogeophysical systems, interact together with environmental factors (e.g., climate change, CO2 and land use change) in norther high latitudes over decadal to century time scales. (2) Investigating the effects of large scale production of biofuel energy crops and conventional crops on climate. The specific objectives are to use an ESM to quantify the crop yields of energy crops and conventional crops and their implications for greenhouse gas emissions, water use, as well global climate.
