Johannes is a Lecturer in the Department of Materials and a Royal Society University Research Fellow in the Department of Materials and the Department of Physics at Imperial College London. He is also the Assistant Director of the Centre for Doctoral Training in Theory and Simulation of Materials at Imperial College.
He obtained a Ph.D. in physics from Cornell University in 2010 working in the group of Prof. Tomas Arias. From 2010 to 2014, he was a postdoctoral researcher at UC Berkeley and Lawrence Berkeley National Lab in the groups of Prof. Steven Louie and Prof. Marvin Cohen.
His research interest lies at the interface of theoretical condensed matter physics, chemistry, materials science and scientific computing. He studies the properties of matter using a variety of tools ranging from first principles many-body perturbation theory (GW/BSE method) and density-functional theory to classical force field methods and continuum theories. Currently, he is working on new materials for photovoltaics (for example, polymers), oxide-water interfaces for photoelectrochemistry, two-dimensional materials for electronics and energy storage (such as, graphene-based supercapacitors) and iron-based superconductors.
