About Me

I have been a visiting scholar in Prof. Greeley's group since October 2012 and work at the Leadership Computing Facility in Argonne National Laboratory. I was previously a postdoctoral fellow in the Interfacial Materials group of the Materials Science Division at ANL. I received my Ph.D. from The Ohio State University in Columbus, Ohio, under the direction of Prof. John Wilkins. My undergraduate studies took place in the physics and astronomy departments at the University of Texas of Austin.

Project Description

I investigate the interactions of electrons through quantum mechanical modeling using methods such as density functional theory and quantum Monte Carlo. I apply these models to systems of interest including chemical catalysis in noble metals, multiferroics in complex oxides, and point defects in semiconductors. I seek to understand more deeply many open questions in these models including electron exchange and correlation energies and pseudopotential representation of core electrons.
