Edwin Romeijn's research area is optimization theory and applications, and he teaches courses in optimization and stochastic processes. His recent research activities mainly deal with systems arising in radiation therapy treatment planning and supply chain management. In radiation therapy treatment planning, the main goal is to develop new models and algorithms for efficiently determining effective (i) treatment plans for cancer patients who are treated using radiation therapy, and (ii) treatment schedules for radiation therapy clinics. In supply chain optimization, his main interests are in the integrated optimization of production, inventory, and transportation processes, in particular in the presence of demand flexibility, limited resources, perishability, and uncertainty.
