Prof Paul S. Spencer received a B.Sc. degree in applied physics and a Ph.D. degree in electronic engineering from the University of Bath, in 1990 and 1994, respectively. From 1994 to 1996, he was a research assistant at the University of Bath. In 1996, he moved to Bangor becoming a lecturer in 1998, a senior lecturer in 2003 and receiving a Personal Chair in 2006. In 2007 he was appointed Head of the School of Electronic Engineering, a post he held for seven years. In 2009 he was appointed Head of the College of Physical and Applied Sciences and in 2017 he was appointed Dean of the College of Environmental Sciences and Engineering

His main research interests are semiconductor laser dynamics, optical feedback effects, pulse propagation, and optical waveguide properties of optoelectronic devices. He has been an author on over 100 journal papers and 140 conference papers and is a regular reviewer archival journals. In 2000 he won the Science, Engineering and Technology (SET) best engineering poster award.
