Deniz Aksen is a Professor in the Department of Business - Operations Management and Information Systems at Koç University's College of Administrative Sciences and Economics. His research focuses on optimization problems in logistics, supply chain management, and facility location, with particular expertise in vehicle routing problems and interdiction models. Education: PhD in Operations Research from Purdue University (2003) Master's Degree in Industrial Engineering from Boğaziçi University (1996) Bachelor's Degree in Industrial Engineering from Boğaziçi University (1994) Professor Aksen's research centers on combinatorial optimization with applications in logistics and supply chain management. His work spans vehicle routing problems , facility location , interdiction models , and metaheuristic solution methods . He has made significant contributions to the understanding of r-interdiction problems where facilities must be protected against potential attacks, and has applied his methods to practical contexts including election logistics and waste collection systems . His approach often combines mathematical modeling with innovative heuristic and metaheuristic techniques to solve complex optimization problems that arise in real-world settings. Analysis of Professor Aksen's recent publications reveals a strong focus on bilevel and trilevel optimization models applied to security and logistics problems. His work frequently addresses the interdiction theme - studying how to optimally protect facilities against potential attacks or disruptions. The research shows increasing sophistication in modeling approaches, moving from basic vehicle routing problems to complex multi-level decision frameworks that incorporate protection and interdiction considerations. His applications span diverse domains including election logistics, waste management, and critical infrastructure protection, demonstrating the versatility of his methodological contributions to operations research. Professional Activities: Member of editorial boards for operations research journals Reviewer for leading journals in operations research and management science Active participant in international conferences on optimization and logistics
