Dearden, Geoff - University of Liverpool

个人简介

In addition to my research and teaching interests, I have carried out knowledge exchange activity in laser technology for the University since 1995, in support of regional industry SMEs. I am a former employee of BAE Systems and now have more than 25 years academic and industrial experience in photonics R&D. I have over 175 scientific publications (including 75+ journal papers and 4 patents awarded / published) and have supervised 25+ PhD students. I am currently PI on the EPSRC project Towards In-Combustion Event Feedback control in laser ignition (TICEF) and the ERDF funded project Knowledge Exchange in Laser Engineering (KE-Las). I was previously CI on TSB projects PRISM, PARALASE, SUADIP and DL-POP, on EPSRC projects FLAVIIR and ULTRAFAST, on DTI-LINK Foresight project LASIIC and on Carbon Trust, EPSRC KTA, EU Marie Curie and Northern Way (Printed Electronics) awards. I have worked with well over 100 companies, and on contract R&D with partners including BAE Systems, QinetiQ, Honda, SureSensors, GEM and many SMEs.
