Hande Benson

Hande Benson is an Associate Professor and Assistant Department Head in the Department of Decision Sciences and MIS. She serves as director of the College’s Business and Engineering program and teaches in the undergraduate and graduate programs in Business Analytics and Operations and Supply Chain Management.

Dr. Benson received her Ph.D. in Operations Research and Financial Engineering from Princeton University and continued as a postdoctoral fellow for the Princeton Environmental Institute. She joined Drexel after faculty positions at Rutgers University and the United States Naval Academy. Throughout her career, she has consulted for numerous financial firms, the production industry, and local governments, and she is a core faculty member for LeBow’s Corporate and Executive Education programs.

Dr. Benson’s research interests are in optimization, particularly in addressing modeling and computational challenges for large-scale optimization problems. She is a co-developer of the popular optimization software LOQO, and her research group has recently released the Matlab-based optimizer MILANO.
