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.
