Ieke (I.M.W.) Schrader is a researcher at the University of Twente, specializing in Operations Research and Management Science. Her work focuses on improving capacity planning and scheduling in the judicial system through mathematical modelling and decision-support methods. As part of the Tijdige Rechtspraak project, she develops (optimization) models that help courts reduce waiting times, improve resource allocation, and balance workloads. Her research interests include mixed-integer linear programming, multi-objective optimization, timetabling, and performance management in complex service organizations.
