Andreas Wipf is full professor at the Friedrich-Schiller-University (FSU) of Jena, Germany, where he teaches many courses related to theoretical physics. His research focuses on quantum field theory in the continuum and on lattice, structural aspects of quantum theory, quantum systems under extreme conditions, conformal and supersymmetric field theories, and the role of symmetries and symmetry breaking in theoretical physics. He obtained his Diploma at the Department of Physics at ETH Zurich, and his Ph.D. at the Institute for Theoretical Physics of the University of Zurich. He covered positions as postdoctoral fellow, assistant professor, and Privatdozent at the Dublin Institute for Advanced Studies, Los Alamos National Laboratory, Max-Planck-Institute for Physics (Werner-Heisenberg-Institute) in Munich, and at ETH Zurich where he habilitated in 1995. Then, he moved to Jena as full professor and has been Director of the Institute for Theoretical Physics, Dean of the Physics and Astronomy Faculty, Spokesman of the research training group on gravity, quantum field theory, and mathematical physics. He co-authored the textbooks "Theoretische Physik" (Springer Spektrum, 2015), which presents all theoretical physics up to the bachelor's degree and beyond, and "Theoretische Physik 3 | Quantenmechanik" (Springer Spektrum, 2018).
