Summary
Johannes is a Reader in Theory and Simulation of Materials and a Royal Society University Research Fellow in the Department of Materials at Imperial College London. He obtained a Ph.D. in physics from Cornell University in 2010. Before joining Imperial in 2014, he was a postdoctoral researcher at UC Berkeley and Lawrence Berkeley National Lab.
His research is focused on electronic excitations in complex materials. Recently, his group has developed novel methods to model excited states in twisted bilayers of two-dimensional materials, such as twisted bilayer graphene and twisted homo- and heterobilayers of transition metal dichalcogenides. Other areas of interest include hot carrier generation in nanoplasmonic materials and simulating core and valence electron spectroscopies via the GW and GW cumulant approach or the Delta-SCF method.
