Research Interests
Random Matrix Theory
Random Matrix Theory (RMT) has recently found numerous applications in signal processing, finance, and bioinformatics. We are applying the tools of RMT to the study of disordered solids, with a particular emphasis on disordered organic photovoltaics. We are approaching this problem both top-down and bottom-up. On one end, we are performing direct QM/MM simulations of organic materials and trying to map the data onto RMT methods. On the other end, we are attacking simple models of disordered systems semi-analytically with tools from RMT.
Sampling
I'm working on a reweighting method to improve the convergence of averages that use configurations generated by MM methods. In addition, I'm trying to improve the nested Monte Carlo scheme in order to make it competitive with direct QM/MM.
