He is also a Research Fellow at the and the German Economic Research Institute (DIW Berlin) and Visiting Lecturer at the Technical University of Berlin. He is an Associate Editor of the journal Optimization and Engineering and is currently serving as Chair for the Energy Cluster and Vice Chair for Linear and Conic Optimization for The Institute for Operations Research and Management Science. His research is on formulating and solving optimization and game theory models applicable to large-scale systems. Such systems arise when modeling problems in energy and environmental markets, public health, and healthcare. He also models engineering design and develops novel algorithms along with supporting mathematical theory.
