About me

I completed my MSci in physics at Imperial College London (2006-2010). After my undergraduate studies I joined the theory and simulation of materials (TSM) centre for doctoral training (CDT) and completed an MSc (2010-2011) and PhD (2011-2014). For my PhD I studied the electronic stopping power (this has units of force), which is the rate of electronic excitation with respect to the distance travelled, for ions travelling along fixed crystallographic directions in silicon (Si) at constant velocity. As part of my PhD I used time-dependent DFT, time-dependent tight binding and perturbation theory. In 2012 I worked for three months at Lawrence Livermore national laboratory in California and I have continued to collaborate with them.

Research

I am studying laser irradiation of silicon thin films. In experiments the silicon is oxidised leading to the confinement of the silicon by silica. I am currently constructing a model to include the effects of the silica on the silicon, while keeping the computational cost to a minimum and general enough to be transferable to other molecular dynamic systems (e.g. tungsten and tungsten oxide). The model will be parameterised by using a combination of first principle, molecular dynamics and finite element calculations.
