Peter Puschnig is Associate Professor in Theoretical Solid State Physics working at the Institute of Physics at the University of Graz. In his research group, he is dealing with ab-initio electronic structure calculations based on density functional theory (DFT) and its application to crystalline solids, surfaces and interfaces. In recent years, the focus has been on understanding the electronic properties of organic/metal interfaces and in the development of photoemission orbital tomography. He is teaching various theory courses in the Bachelor's and Master's study programmes in physics.
