I work on planet formation simulations, primarily modelling migration of gas giants in the outer parts of early, massive discs as well gas and dust accretion onto these objects.

Personal details

I completed my MPhys at the University of Durham in June 2016. For my Masters project I researched the outburst limit cycle in Low Mass X-Ray Binary Transients woith Professor Chris Done. I wrote a 1-D explicit disc code in order to model this behaviour with an empirical opacity form to model the Hydrogen ionisation instability and included additional physics in the form of irradiation from the inner disc and the depleting effect of disc winds.

I began my PhD in Leicester in September 2016 under the supervision of Professor Sergei Nayakshin. I primarily use the SPH code GADGET-3 to model dust accretion onto giant protoplanets at wide (~50-100 AU) separations and to study the resultant levels of metalicty enhancement. We use an implicit dust drag scheme in order to reduce computational costs. I have presented this work with posters at conferences in St Andrews and Cambridge and given a talk in Garching. I hope to extend my research into the modelling the interactions between gas and dust in protoplanetary disc environments and to strengthen the links between my research and observational results.

I am also a seminar leader for the level 2 physics course.

Outside of work I am a keen swing dancer and I am heavily involved in running the society in Leicester, you should come along!
