Steve Collins BSc MA PhD

Steve Collins received a BSc in Theoretical Physics from the University of York in 1982 and a PhD in Theoretical Physics from the University of Warwick in 1986. He was then employed as a government research scientist, working on semiconductor device physics and analogue circuit design.

In November 1997, Steve moved to the Department of Engineering Science at the University of Oxford. Initially he continued his work on wide dynamic range CMOS cameras. However, in 2012 he started working on various approaches to improving the performance of receivers for Visible Light Communications and this is now the focus of his research.

In 2012 Steve started working on receivers for visible light communications based upon arrays of single photon avalanche diodes. Then in 2014, he was the lead author on the first paper to suggest that fluorescence could be exploited to create large-area, wide field-of-view optical concentrators for visible light communications.

The current focus of his research interests is the development of these two technologies and their application to visible light communications and contamination detection in the food industry and hospitals.

I am open to supporting DPhil students with an interest in:

• Receivers for Visible Light Communications
• Sensitive optical detectors that can detect contamination in the food industry and hospitals.
