I am currently Head of Condensed Matter Physics here in Oxford.
I am a Professor of Condensed Matter Physics at Oxford University working on quantum optoelectronics and the time-resolved properties of quantum matter. I am also a tutorial fellow at The Queen’s College, Oxford, where I am one of two tutors teaching approximately 22 physics students
I have been a permanent member of staff at Oxford since 1990.
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.
I have just been awarded a grant by EPSRC entitled "Plasmon-enhanced light emission from hybrid nanowires: towards electrically driven nanowire lasers". This will commence on 1st August, 2021.
