Particle-based sediment transport
Development of modelling approaches that represent sediment as interacting particles and connect particle trajectories, forces and contacts to reach-scale transport and morphological change.
Projects
Selected themes that illustrate how I connect physical modelling, numerical methods and research software.
River ice dynamics
Research concepts for horizontal ice transport, ice-jam initiation and breakup, water-ice-sediment interaction, and the mechanical response of connected or fragmented ice.
Thixotropic and non-Newtonian flow
Development of constitutive models and transported structural variables for materials whose rheology evolves with flow history.
Linear solvers and numerical infrastructure
C++ and Fortran infrastructure for sparse matrices, Krylov methods, multigrid and algebraic multigrid preconditioning.
Curvilinear-grid modelling
Numerical methods and grid-generation concepts for complex three-dimensional domains, boundary treatment and free-surface flow.
Large-scale environmental simulation
Use of parallel computing and national HPC resources to study computationally demanding multiphysics and multiscale problems.
