I am a research scientist at the Oak Ridge National Laboratory near Knoxville, Tennessee. My current work is developing computational models to simulate the fast pyrolysis of biomass in fluidized reactors. This research is part of the Consortium for Computational Physics and Chemistry for the U.S. DOE Bioenergy Technologies Office. I am also involved in various battery simulation activities as part of the Computer Aided Engineering for Batteries project. As an enthusiastic developer, I organize the Knoxville CocoaHeads and KnoxPy programming groups.
