I am a postdoc in the group of Prof. Nicola Marzari at EPFL in Switzerland.
Broadly, I am interested in how we can improve the performance of density functional theory (DFT). Inspired by known properties of the exact functional and the systemic errors of DFT, one can construct inexpensive corrections to DFT that drastically improve its performance.
Most recently, I have developed the
koopmans code, a package that implements Koopmans functionals. By imposing a generalized piecewise energy condition, these functionals obtain spectral properties with comparable accuracy to GW at a fraction of the cost.
My other research interests include linear-scaling density functional theory and methods for treating strong correlation (such as dynamical mean field theory).
