I am currently Emeritus Professor of Condensed Matter Physics here in Oxford.
I work on quantum optoelectronics and the time-resolved properties of quantum matter. I was also a tutorial fellow at The Queen’s College, Oxford, where I was one of two tutors teaching approximately 22 physics students. I am now an Emeritus Fellow at Queen's.
As I am now retired I will not be taking on any new post doctoral researchers or any new students.
I was a permanent member of staff at Oxford from 1990 until 2025.
My main interests have been in making optical measurements on wide-bandgap semiconductors and low-dimensional systems such as quantum dots, wires and wells. Topics currently being investigated include the generation of single photons in the blue, coupling of quantum dot emission at telecom wavelengths to photonic crystals, coupling of various quantum emitters to discrete cavities. Past work focussed on coherent electron-hole dynamics, excitonic dynamics in wide band gap materials such as GaN and InGaN, and gain mechanisms in bulk and quantum well lasers. Please have a look at my publication list for references to relevant recent work.
Full details of my research activities can be found on my group website in the Quantum Optoelectronics research group tab under my photo above.
My final EPSRC grant entitled "Plasmon-enhanced light emission from hybrid nanowires: towards electrically driven nanowire lasers" ran out recently.
