Research areas.

PDE, differential geometry, spectral theory. 

Current research interests.

Geometric scattering theory, microlocal analysis (resolvents, Eisenstein functions and distorted plane waves, scattering operators) -
Conformal geometry (Fefferman-Graham program, AdS-CFT) -
Hyperbolic geometry and Teichmüller theory (geometrically finite hyperbolic 3-manifolds, renormalized volume and Chern-Simons invariants) -
Geometric and spectral invariants (determinant of Laplacians, eigenvalues, renormalized volume) -
Quantum chaos and resonances (semiclassical measures, localisation and counting resonances) -
Dynamical zeta functions and hyperbolic dynamical systems (Selberg trace formulas in non-compact settings, Ruelle resonances for flows, cohomological equations) -
Inverse problems, analytic (Calderon problem, spetcral rigidity) and geometric (X-ray transform, boundary rigidity) -
Harmonic analysis (Riesz transform, multipliers, restriction theorems), particularly in geometric settings -
Liouville gravity, random metrics on Riemann surfaces (Gaussian free field, Gaussian multiplicative chaos, Polyakov partition function) -
