I work on theoretical numerical analysis in a broad sense, in particular, structure-preserving methods and finite element exterior calculus.
The vision of my current research includes:
1) connections between homological algebra, geometry, and mathematical and numerical analysis; geometric foundations of continuum mechanics,
2) discretizations of PDEs and discrete theories (discrete geometry, discrete mechanics etc.),
3) structure-preserving approaches for solving the Einstein equations in general relativity, with potential applications in computational astronomy and gravitational-wave sciences,
4) advanced numerical methods (high order methods, preconditioning etc.) and applications (fluid and solid mechanics, magnetohydrodynamics etc.),
5) scientific computing, computation of spectrum, localization.
