Research Topic: Optimization in logistics and supply chain management, especially using metaheuristics.

 

Kenneth Sörensen received his PhD from the University of Antwerp in 2003. From 2009, he is employed as a Research Professor (ZAP-BOF hoofddocent) of the Faculty of Applied Economics of the University of Antwerp. He is founder of the ANT/OR research group. His research focuses on applications of optimization, especially using metaheuristics in logistics and supply chain management, production planning and various other fields. Kenneth Sörensen is founder and member of the coordinating team of EU/ME - the metaheuristics community (metaheuristics.eu), the largest online forum for metaheuristics researchers.
