Curriculum Vitae

About Me

I am a post-doctoral fellow in the Mathematics Department at the University of British Colombia.

I got my PhD degree at Dalhousie in August 2021 under the supervision of Theodore Kolokolnikov.

Research

My research lies in dynamical systems and mathematical modelling. A focus of my work has involved

analysis of pattern formation in reaction-diffusion systems using asymptotic and singular perturbation

techniques.
