I have specific modeling experience with general circulation
models (GCMs) and regional climate models (RCMs). Most of my research with these models has
focused on paleoclimate simulations and data-model comparisons, especially
during the Holocene and Last Glacial Maximum (LGM). I used the National Center for Atmospheric
Research (NCAR) Community Climate Model Version 1 (CCM1) to explore the
sensitivity of the climate system to different forcing mechanisms, such as ice
sheets, orbital insolation, and atmospheric CO2 increases (Felzer et
al., 1995, 1996, 1998, 1999) and the GENESIS model to study the hydrology of
the paleoArctic environment (Felzer et al., 2000; Felzer, 2001). During my postdoctoral research at the

I am currently doing experiments with the latest NCAR model, CESM, on my own Beowulf cluster, Lehigh’s Corona cluster, and NSF’s Yellowstone cluster. My experiments involve changes to the CLM-CN land model to explore the role of carbon dynamics in the coupled land-atmosphere system.
