dr.ir. W. Olthuis (Wouter)

Wouter Olthuiswas born in Apeldoorn, the Netherlands. He received his MSc. degree in electrical engineering from the University of Twente, Enschede, the Netherlands on the subject of thermally excited resonating silicon membrane pressure sensors. Then, he joined the Center for MicroElectronics, Enschede (CME) doing research on inorganic electret materials for subminiature silicon microphones. Subsequently he started his PhD project and received the PhD degree from the Biomedical Engineering Division of the Faculty of Electrical Engineering, University of Twente, in 1990. The subject of his dissertation was the use of iridium oxide in ISFET-based coulometric sensor-actuator devices. Since 1991 he has been working as an Assistant Professor in the Laboratory of Biosensors, part of the MESA⁺ Research Institute of the University of Twente and as such co-supervising many projects on both physical and (bio)chemical sensors and sensor systems for medical and environmental applications. Currently, he is Associate Professor in the BIOS Lab-on-Chip group of the MESA⁺ Institute of Nanotechnology and is as such responsible for the theme Electrochemical sensors and Sensor systems. He has (co-)authored over 180 papers (h=40) and 7 patents. From 2006 until 2011 he has also been the Director of the Educational Programme of Electrical Engineering at the Faculty of Electrical Engineering, Mathematics and Computer Science at the University of Twente. In 2011, he was appointed as officer on education in the executive committee of the IEEE Benelux section.
