I am presently a Ph.D. student in the Mathematics Department at UBC, where I am a member of the Probability Group. My supervisor is Gordon Slade.
Broadly speaking, I am interested in problems involving methods from probability theory and analysis. I am currently studying certain models of statistical physics, in particular the lattice |φ|4 spin model and the weakly self-avoiding walk
with a nearest-neighbour contact attraction. My work at present involves applying a rigorous renormalisation group method in order to understand the appearance of critical behaviour in these models.
See my research statement for more information.
