Academic Career and Research Areas
Prof. Thielen's (*1984) field of research is Discrete Optimization. A special focus is on modeling and solving optimization problems on networks as well as on approximation algorithms for multiobjective and parametric optimization problems. In practical applications of his research, he deals, among other things, with optimization problems in hospitals, such as staff scheduling for physicians.
Prof. Thielen studied mathematics at the Technical University of Kaiserslautern and the University of Cambridge (UK). After receiving his PhD in mathematical optimization in 2010, he worked at the Department of Mathematics at the Technical University of Kaiserslautern, first as a postdoc and then from 2013 to 2019 as a junior professor. In October 2019, Prof. Thielen was appointed to the professorship of complex networks at TUM Campus Straubing.
