Current research areas:
Pseudodifferential calculi, for manifolds with boundary and with spectral parameters. Geometric analysis. Asymptotic trace expansions of parameter-dependent operators, the geometric interpretation of the coefficients. The logarithmic and nonlocal terms. The noncommutative residue and the canonical trace. The zeta coefficients. Spectral boundary conditions in Brane theory. Applications of pseudodifferential methods to Navier-Stokes problems. Extension theory and boundary problems for elliptic operators. Krein resolvent formulas. Nonsmooth boundary value problems. Krein-like extensions (without regularity). Spectral asymptotics for problems with jumps. Fractional Laplacians, heat kernels, regularity properties on a domain.
