Biography

I am an Associate Professor in the Department of Applied Mathematics at the University of Waterloo. Before coming to Waterloo, I had the pleasure of gaining research experience at the Mathematical Institute and Department of Physics, University of Oxford, and at the Department of Chemical & Petroleum Engineering, University of Pittsburgh. My research interests are in modelling and simulating various microscale fluidic systems, such as flagellated microorganism motility, control of bio-inspired microrobots, and chemo-hydrodynamic pattern formation. I work primarily with singularity-based methods for numerically solving the equations of Stokes flow and apply these methods to systems incorporating elastic, magnetic, or electrokinetic interactions.
