Research
My research is in numerical analysis and scientific computing for partial differential equations, with applications in fluid dynamics, magnetohydrodynamics (MHD), and kinetic plasma physics.
Structure-preserving numerical methods
My expertise includes:
- high-order finite element and summation-by-parts (SBP) finite difference methods;
- conservation, positivity, invariant-domain preservation, entropy inequalities, and nonlinear stability;
- convex limiting, flux-corrected transport, and residual or entropy viscosity;
- nonlinear stabilization for shocks, steep gradients, and multiscale problems.
Fluid dynamics and magnetohydrodynamics
My expertise includes:
- compressible and incompressible flow, nonlinear conservation laws, and ideal, viscous, and resistive MHD;
- high-order and continuous Galerkin discretizations;
- shock capturing and nonlinear stabilization;
- invariant-domain- and entropy-stable methods;
- reliable simulation of high-speed and under-resolved flows.
Kinetic plasma models and fusion
My expertise includes:
- Vlasov–Poisson and Vlasov–Maxwell systems, kinetic transport, and coupled plasma-field models;
- structure-preserving and positivity-preserving discretizations;
- high-order finite element and SBP methods;
- low-rank approximations for high-dimensional phase spaces;
- matrix-free and GPU-accelerated scientific computing.
Additional interests
My broader interests include multiscale and homogenization methods, adaptive computation, parabolic regularization, and reduced representations for high-dimensional PDEs.
