Han van de Waterbeemd studied physical organic chemistry at the Technical University of Eindhoven and did a Ph.D. in medicinal chemistry at the University of Leiden, The Netherlands. After a post-doc with Bernard Testa at the University of Lausanne, Switzerland, he became a faculty member for 5 years and taught medicinal chemistry to pharmacy students at the universities of Berne and Basel, Switzerland. In his pharmaceutical career he worked for Roche, Pfizer and Astra-Zeneca where he is now global project leader of their platform for in silico predictions of ADME/Tax properties. He published more than 133 peer reviewed papers and book chapters, and (co-) edited 11 books. His research interests include the role of physicochemical and structural molecular properties in drug disposition and in silico modeling of ADMET properties.
