Merlin Pelz
Welcome to my personal website! I'm a Ph.D. candidate in Applied Mathematics at the University of British Columbia, advised by Prof. Michael J. Ward and Prof. Daniel Coombs. In my work, I'm focusing on further developing mathematical biology with nonlinear dynamics, asymptotic analysis and (S)PDE theory. Specifically, we are currently working on the emergence of symmetry-breaking in compartmental-reaction diffusion systems.

Further Research & Work Experience
Research
Here is a selection of figures to my research. For the corresponding developed theory, please go to the tab Publications. The figures for the 1-D domain were created with Julia and the figures for the 2-D domain with FlexPDE. Intracellular kinetics used are FitzHugh-Nagumo, Gierer-Meinhardt and Rauch-Millonas reaction kinetics.
