Pierre joined Philips Research in 1980. His research covered (ultra-low temperature) electrical transport, weak and strong electron localization and magneto-resistance in ultra-thin films and multilayer stacks. Furthermore, quasi one-dimensional MOS structures were fabricated to study quantum transport phenomena; the electrical conductance of MOSFETs with sub 50 nm metal gates was measured at temperatures down to 10mK.

In 1985 he started collaborating with TU-Delft and Redhill Laboratories on quantum transport in nano-scale AlGaAs-GaAs MESFET and HEMT devices.

From 1985 till 2001 he was involved in CMOS process integration, device physics and the reliability of advanced CMOS devices. He was responsible for the development of 0.5-µm CMOS and 0.25-µm CMOS front-end technologies. In the area of device physics the study of room temperature quantum effects in advanced MOS devices proved important; these effects are of key importance for present day MOS devices.

From 1995 to 1998 he worked on a high-density ultra low-cost one-time programmable memory technology (‘singing chip’) which was re-used by Matrix Semiconductor and is now owned by SanDisk.

From 1998 to 2001 he worked on the impact of device scaling on the RF performance of RF-CMOS. He was the first non-US general chair of the International Electronics Devices Meeting (IEDM), which is the world’s premier forum for CMOS technology.

From 1992 till 2001 he was part-time professor at the faculty of Electrical Engineering of the University of Twente.

From 2001 till 2006 was active in the field of standards in optical recording. He was a member of the team that developed DVD+R recordable Double Layer technology which is now available in almost every PC and CE device.

From 2006 on he has been involved in medical research in the field of Advanced Life Support and Cardio Pulmonary Resuscitation (CPR). He was project leader of the automated CPR project till 2009. His present interests are in the field of personalized CPR, modeling of CPR, treatment of reperfusion damage and advanced patient monitoring.

He is (co) author of more than 120 published articles and conference papers and is (co) inventor of 25 US patents.
