What We Do

We develop and employ theoretical and computational methods including Density Functional Theory, Many-Body Perturbation Theory and quantum dynamics for open systems, to understand and predict realistic 

complex materials’ properties including optical, spin and electron transport and catalytic properties at the atomistic levels, for energy conversion and quantum information applications.
