Research:

Brenda's research revolves around developing novel quantum Monte Carlo techniques capable of studying systems in which quantum statistics assume a pivotal role. Over the past few decades, a number of mean field theory-based techniques, Density Functional Theory (DFT) chief among them, have grown exceedingly popular as economical ways of determining the properties of quantum materials. Despite their popularity — and success, these techniques often trade accuracy for computational efficiency. In contrast, quantum Monte Carlo techniques promise much higher levels of accuracy for only a modest increase in computational cost. Brenda's research aims to develop the theoretical and algorithmic tools necessary for making quantum Monte Carlo a practical option for many electronic structure, low-temperature, and/or high-pressure calculations. While at the lab, Brenda hopes to apply the algorithms she develops to the study of hydrogen plasmas and the actinides.
