Johannes Voss is staff scientist at the SUNCAT Center for Interface Science and Catalysis at SLAC National Accelerator Laboratory. He leads the SUNCAT group on electronic structure methods. The group develops reliable exchange-correlation functionals for computational surface science and efficient beyond density functional theory approaches. The scope of these developments is an improved computational description of materials properties with an emphasis on materials for energy conversion and storage.
Within the Ultrafast Catalysis FWP at SLAC, he leads the efforts of X-ray spectra simulations for understanding of ultrafast surface chemistry as observed using free-electron lasers.

Johannes Voss is regular guest lecturer at Stanford in electronic structure and heterogeneous catalysis classes (CHEMENG-444-01/ENERGY-256-01 and CHEMENG 142/242).
Topics covered include the basics of density functional theory & beyond and how this method can be applied to predict reaction rates, thermodynamic stabilities, and other materials properties.
