Johann Ostmeyer was a PhD Student in theoretical physics at the Helmholtz-Institute für Strahlen und Kernphysik at the University of Bonn. His topic was the investigation of the Hubbard Model on the honeycomb lattice using Hybrid Monte Carlo and Tensor Network techniques. Then, he worked at The University of Liverpool, UK. Now he is a CRC NuMeriQS project leader back at the University of Bonn.
