• Designed and performed density functional theory (DFT) calculations to investigate problems in point defect energies, point defect diffusion barriers, molecular catalysis, and crystallographic phase transitions..
• Discovered a possible mechanism for room-temperature vacancy diffusion contributing to a specific device failure mode in AlGaN HEMT devices. Expected relevance for other high-field semiconductor devices with charged.
• Identified Fe-porphyrin as a potential self-cleaning catalyst for room-temperature reactions between DNT and atmospheric O2. Characterized reaction pathways and activation barriers for the reaction.
• Configured and managed computations on large supercomputing clusters.
• Regularly prepared and presented both oral and published reports of my work for a broad audience.
