I'm a research scientist at the Oak Ridge National Laboratory in 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 Consortium for Advanced Battery Simulation project. As an enthusiastic developer, I organize the Knoxville CocoaHeads and KnoxPy programming groups.

Applications


WeathrClip provided current weather conditions, 5-day forecast, hourly forecast, and precipitation radar for the Mac and iPhone. I discontinued this app because the Weather Underground API is no longer available.

Un1ts was a comprehensive unit converter for the Mac written in Objective-C. I’m currently working on a new version of the app written in Swift.
