Research interests

My main expertise is in applied mathematics, modelling water wave propagation in the presence of floating bodies (like ice sheets, for example). I have other interests in elasticity, wave propagation in random media, and mathematical techniques such as the Wiener-Hopf and residue calculus techniques. I am currently working on including the interactions between waves and sea ice in the new sea ice model neXtSIM that is being developed at NERSC.

Project deputy leader of the following projects

  1. neXtWIM: Waves in a next-generation sea ice model
  2. SWARP: Ships and Waves Reaching Polar Regions
  3. WIFAR: Waves-in-Ice Forecasting for Arctic Operators
