Albert J.P. Theuwissen was born in Maaseik (Belgium). He received the degree in electrical engineering and his PhD from the Catholic University of Leuven (Belgium) in 1977 and 1983 respectively. In 1983, he joined Philips Research Labs, Eindhoven (the Netherlands), as a member of the scientific staff. In 1991 he became Department Head of the division Imaging Devices of Philips.

He is author or coauthor of over 120 technical papers in the solid‑state imaging field and issued several patents. He is co‑editor of the IEEE Transactions on Electron Devices special issues on Solid‑State Image Sensors, May 1991, October 1997, January 2003 and November 2009, and of IEEE Micro special issue on Digital Imaging, Nov./Dec. 1998. In 1995, he authored a textbook Solid‑State Imaging with Charge‑Coupled Devices.

He acted as general chairman of the IEEE International Workshop on CCDs and Advanced Image Sensors in 1997, 2003, and 2009. He is founder of the Walter Kosonocky Award, which highlights the best paper in the field of solid-state image sensors. Since 1999 he is a member of the technical committee of the International Solid-State Circuits Conference. He has been elected to be International Technical Program Vice-Chair and Chair for respectively the ISSCC 2009 and ISSCC 2010.

In March 2001, he was appointed as part-time professor at the Delft University of Technology, the Netherlands and in April 2002, he joined DALSA Corp. After he left DALSA in September 2007, he started his own company, Harvest Imaging, focusing on consulting, training, teaching and coaching in the field of solid-state imaging technology.

In 2006 he co-founded (together with his peers E.Fossum and N.Teranishi) ImageSensors, Inc. (a California non-profit public-benefit company) to address the needs of the image sensor community.

Recently in 2008, he received the SMPTE’s Fuji Gold medal for his contributions to the research, development and education of others in the field of solid-state image capturing. He is member of editorial board of the magazine “Photonics Spectra”, an IEEE Fellow and member of SPIE.
