Research

Our research is at the intersection of fundamental theory of materials, development of accurate electronic structure algorithms and informatics tools aimed at automated computational design of new functional materials. We prioritize relevance for technological applications: solid-state batteries, thermoelectrics, ferroelectrics, 1D/2D quantum electronics, functional polymers and catalysts.
