Christopher Hojny is an assistant professor working at TU/e since October 2019. His main research topic is the development of efficient techniques to handle symmetries in mixed-integer programs. Besides symmetry handling, he is also interested in theoretical properties of integer programs (e.g., the existence of formulations with certain properties) and developing integer programming approaches to solve combinatorial optimization problems. Christopher is also a co-developer of the academic solver SCIP.
