Personal statement
I am a Senior Research Fellow in the Department of Physics, where I have worked in the Semiconductor Spectroscopy and Devices research group since 2000. Prior to this, I studied at Imperial College London, Albert Ludwigs Universität Freiburg and Durham University. My PhD and post-doctoral work at Durham involved the use of scanning electron and optical beam techniques to study thin-film CdTe solar cells. I now apply similar techniques to characterise materials, nanostructures and devices made from group III nitride compounds.

Research interests
My research is focussed on the use of spectroscopic and microscopic methods in the analysis of semiconductors. The main materials of current interest to me are those based on the group III nitride quaternary system, AlxGayIn(1-x-y)N, and in particular nano-scale structures based on them. These have applications in many different areas, including solid-state lighting, data storage, communications and water purification. The techniques I use to study these materials include photoluminescence and electroluminescence spectroscopy, as well multiple modes of scanning electron microscopy (such as cathodoluminescence, electron beam-induced current and X-ray microanalysis). I am also interested in the application of multivariate statistical analysis techniques in the processing of the multidimensional data that these experimental methods yield.

- "This Platform Grant (PG) will apply our internationally-leading expertise in structured illumination and hybrid inorganic/organic semiconductor optoelectronic devices to create new opportunities in the rapidly developing field of light-controlled manufacturing. Structured illumination fields can in principle be obtained from both inorganic (GaN) and organic LEDs, implemented on a macroscale via relay optics, or demagnified to a microscale. Novel manufacturing with photopolymerisable materials can firstly involve use of structured illumination as a novel means to control motorised stages. This technique can be combined with pattern-programmable UV excitation for mask-free photolithographic patterning, continuous photo-curing over larger fields, localised photochemical deposition, or other forms of photo-labile assembly. Process variants can also be envisaged in which arbitrarily positioned fluorescent objects or markers are 'hunted', and then subject to beam excitation for photocuring or targeted photoexcitation. This method could be used, for example, to immobilise individual colloidal quantum dots for use as emitters in quantum technology applications. Multifunctional devices with sensing ability, such as organic lasers for explosives detection, represent another excellent example of automated devices operating under remote conditions. Further examples of the envisaged uses of this technology include:
[1] LED microdisplay asset tags for management of high-value objects (artworks, nuclear fuel containers).
[2] Passive asset tags containing unique micro-patterns of fluorescent objects (eg. colloidal quantum dots, organic macromolecules) for higher-volume, anti-counterfeiting applications.
[3] Customisable continuous-flow micro-reactors for fine chemical manufacturing.
[4] Energy harvesting micro-modules to power other autonomous microsystems, where we will focus on organic PV and ambient-radiation (RF) approaches." - 01-Jan-2017 - 30-Jan-2021
