My primary research buzzword is "High Performance Computing". Primarily, this involves studying algorithms and models for computational models which lend themselves to Task-based parallelism, and applying such models to GPUs. Currently I'm working on 'The application of Smoothed Particle Hydrodynamics to GPUs for cosmological simulations' with the Institute for Computational Cosmology. Future work includes testing our models on soon-to-be released hardware and extension of current work to include gravity and other necessary work for full cosmological simulations.

Title: Kinetics of surfactant adsorption to liquid-solid interfaces

Using total internal-reflection Raman spectroscopy, it is possible to selectively obtain spectra of the liquid-solid surface region. This allows the study of a variety of different systems, including surfactant-surfactant and surfactant-polymer mixture interactions, useful for example, to monitor detergency. The technique also allows the study of different surfaces, such as cellulose “synthetic cotton” useful for modelling clothing.

Research Postgraduate in the Department of Physics

Organic Light-Emitting Diodes (OLEDs) have in the past few years found widespread applications as displays for mobile phones and other devices, while another major area of research is the development of OLED technology for large-area solid-state lighting with high efficiency and improved colour rendering.

My work involves the fabrication of OLED devices with the aim of optimising the device structure to improve efficiency and brightness, as well as the development and testing of new materials, often in collaboration with the Department of Chemistry here in Durham.

My incredbily vague research title is 'The effect of the microenvironment on stem cell potential'. My work specialises on how growing cells in 3D yields better, more in vivo like cells compared to growing cells in the traditional 2D wells. I will be analysing the results of a study carried out by my lab showing the differing cell markers (and differing concentrations of those surface proteins) between human embryonic stem (ES) cells and human embryonic carcinoma (EC) cells, each grown in both 2D and 3D, by way of stained sectioning of the resultant teratomas.
