Jaap den Toonder is full professor and Chair of the Microsystems group at Eindhoven University of Technology. Jaap den Toonder studied at Delft University of Technology and got his Masters degree in Applied Mathematics in 1991 (cum laude). He received a PhD degree (cum laude) from the same university in 1996 on a numerical/theoretical and experimental study of drag reduction in turbulent flows by polymer additives. His advisor was professor Frans Nieuwstadt. In 1995, he joined Philips Research Laboratories in Eindhoven, The Netherlands, where he started working in the field of the mechanics of solid materials. He worked on a wide variety of applications, such as ceramic capacitors, optical storage systems, IC low-k materials, RF MEMS, soft electronics, biomedical devices, polymer MEMS, and micro-fluidics. In 2008, he became Chief Technologist, leading the R&D program on (micro-)fluidics, and (starting in 2011) materials science and engineering. He was involved in research programs on molecular diagnostics, lab-on-chip, immersion lithography, and energy applications.  Next to his main job at Philips, Jaap den Toonder was a part-time professor at the Materials Technology group of the Eindhoven University of Technology between 2004 and 2013. His current main research interests are: micro-fluidics, out-of-cleanroom micro-fabrication technologies, mechanical properties of biological cells and tissues, nature-inspired micro-actuators, organs on chips   Jaap den Toonder has (co-)authored over 80 scientific papers, as well as over 40 patent applications. He is a member of the Editorial Board of Lab on a Chip.  Ancillary activities: scientific advisor to Philips Research.
