Andreas has recently completed his PhD in Physics at the University of Innsbruck with a thesis on “Positive and Invariant Tensor Decompositions: Approximations and Computational Complexity” under the supervision of Gemma De les Coves and Tim Netzer.

His research lies at the intersection of quantum information and real algebraic geometry, centering around tensor network decompositions and matrix factorizations with positivity constraints and he has also worked in computational complexity theory and categorical probability theory. With his expertise, Andreas is not only a valuable addition to our research group but also to the teaching staff at the Faculty of Mathematics. As postdoctoral university assistant he will teach exercise groups and other courses, starting this winter term with the Quantum Information, Quantum Computing, and Quantum Algorithms proseminar. Moreover, he will contribute to the ERC-CoG project SEQUAM. We wish him a great time with our group in Vienna!
