Research

Overview

My overall research aim is to bring the unparalleled success of density functional theory (DFT) to the calculation of electronic excited states. I am an author of the iDEA code, which models many-body electron behaviour exactly in 1D as well as exact and approximate DFT, time-dependent DFT, and many-body perturbation theories. By modelling electrons in the absence of approximation, I identify why commonly used approximations are unreliable. This insight then informs the development of more reliable approximations for use in practical calculations.
