IEEE Fellows Program

The IEEE Grade of Fellow is conferred by the Board of Directors upon a person with an extraordinary record of accomplishments in any of the IEEE fields of interest. A brief citation is issued to new Fellows describing their accomplishments and the total number selected in any one year does not exceed one-tenth of one percent of the total voting Institute membership. Complete Program Information about the IEEE Fellows Program may be found here.  The Fellow Nomination Process is described here. A Senior member can be nominated in one of four categories: application engineer/practitioner, educator, research engineer/scientist or technical leader.

Robert K. Henderson -  for contributions to solid-state single photon imaging

Robert K. Henderson is a Professor of Electronic Imaging in the School of Engineering at the University of Edinburgh. He obtained his PhD in 1990 from the University of Glasgow. From 1991, he was a research engineer at CSEM, Neuchatel, Switzerland. In 1996, he was appointed senior VLSI engineer at VLSI Vision Ltd, Edinburgh, UK where he worked on the world’s first single chip video camera. From 2000, as principal VLSI engineer in STMicroelectronics Imaging Division he developed image sensors for mobile phone applications. He joined University of Edinburgh in 2005, designing the first SPAD image sensors in nanometer CMOS technologies in the MegaFrame and SPADnet EU projects. This research activity led to volume SPAD time-of-flight products in STMicroelectronics FlightSense series, which perform an autofocus-assist function in more than 150 different smartphone models, recently passing the 1 billion-module milestone. He benefits from a long-term research partnership with STMicroelectronics in which he explores medical, scientific and high speed imaging applications of SPAD technology.
