Alexander Engau has recently joined the Department of Mathematical and Statistical Sciences at University of Colorado Denver as Assistant Professor in Operations Research and Optimization and is co-appointed as Visiting Assistant Professor in Operations Research and Management Sciences in the Faculty of Engineering at University of Waterloo. An alumnus of the National German Merit Foundation, Alexander studied management mathematics and operations research at TU Dresden and Kaiserslautern, Germany (Diploma 05) and Clemson University, USA (MS 04, PhD 07), and subsequently spent a postdoctoral fellowship in the Department of Management Sciences at Waterloo, Canada. His research focuses on the theory and methodology of mathematical programming, optimization, and decision making with a particular interest in interior-point methods and semidefinite relaxations for combinatorial optimization, and has appeared in journals like Management Science, European Journal of Operations Research, and Journal of Optimization Theory and Applications. Also in his spare time Alexander keeps busy with music, sports, and exploring the outdoors.
