Ulrich (Uli) Heisserer, DSM Materials Science Center


Uli is a civil engineer by training who likes to cross borders. After school, he first studied philosophy at the Hochschule for Philosophy SJ in Munich, switched after two full-time years to civil engineering at the TU Munich. There he obtained his PhD on numerical methods (high order finite elements) to solve partial differential equations for nonlinear problems in a German-Israeli project with the Ben-Gurion University. During this time, he still liked to attend selected seminars in philosophy, mainly about social-ethics, bio-ethics, and philosophy of nature. In his free time, he was active in Scouting at many levels. That period ended when he moved to Aachen, where Germany, Belgium and The Netherlands meet. In 2007, he started commuting over the border to the Dutch side to work as a material’s scientist at DSM, a multi-national life science and materials science chemical company with over 20.000 employees that was just listed #2 on Fortune Magazine's ‘Change the World’ list. At DSM’s Materials Science Center, he is involved in understanding and improving polymeric high-performance fibers and composites (Dyneema®) that safe lives in light weight armor. For this effort, he collaborates with many universities and institutions globally. Together with his colleague Harm van der Werff in 2013 Uli won the DSM Science award for ‘Breakthrough modelling of Dyneema® armor performance’ resulting in new fibers now successfully used in improved ballistic vests of many police departments globally. Furthermore, he is working on stiff and string lightweight composites that are necessary to reduce the CO2 emissions of future mobility.
