Research Interests:
 I am interested in using high performance computation to simulate complex systems, and draw physical insights from those simulations. One major example of this is using quantum Monte Carlo calculations to accurately describe the wave functions of realistic models of electrons and nuclei, including the correlations that electrons have with one another. I am particularly interested in drawing conceptual information about how the electrons move in a correlated way. I have also investigated the disordered system amorphous silicon by generating many potential configurations of disordered silicon atoms and examining their properties. By doing this (with my coworkers), we were able to find surprising new configurations of atoms that may be responsible for the trapdominated hole transport found in that system.
