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.
