Oak Ridge National Laboratory
My research focuses on the role that continental runoff plays in the Earth's
climate system. The major tools used to investigate this are climate
system models, and to do the kind of experiments I want to do requires
high performance computers.
Some of My Current Projects
- River Transport Model
- CCSM Climate System Model
- Land cover change experimental simulations
