Hugo J. Woerdeman received his PhD from the Vrije Universiteit in Amsterdam, The Netherlands in 1989. In that same year he was appointed assistant professor at the College of William and Mary. During his tenure there he received a 1995 Alumni Fellowship Award for “Excellence in Teaching,” and he was awarded the title of Margaret L. Hamilton Professor of Mathematics. In December 2004 he joined Drexel University as Professor and Department Head. Over the years, he has had long term stays at the University of California, San Diego, the George Washington University, École Nationale Supérieure des Techniques Avancées, Katholieke Universiteit Leuven, Université Catholique de Louvain, Princeton University, and the University of Waterloo.

Dr. Woerdeman has written four books and served as an editor of four others. He publishes frequently and has authored or co-authored over a hundred articles in top-tier, peer-reviewed international journals.
