Gerard Sierksma studied mathematics, physics, and astronomy at the University of Groningen, where he also obtained his PhD-degree in mathematics (1976). Since then his attention is shifted towards practical applications of mathematical techniques, especially to logistics. During the last years he specialized in the design of decision support computer systems for industry and (top)sports.
Since 2000, full professor of Quantitative Logistics at the Faculty of Economics and Business, and since 2010 honorary professor. R&D director of Team Support Systems / ORTEC. In 2008 elected as Vice Chairperson of INFORMS on SpORts. Research fellow of the SOM Research School, and fellow of the Canadian Institute of Combinatorics and its Applications.
