Current Research and Scholarly Interests

My research concentrates on topics in two broad areas of applications of microlocal analysis in which, partly with collaborators, I introduced new ideas in recent years: non-elliptic linear and non-linear partial differential equations (PDE), typically concerning wave propagation or other related phenomena, and inverse problems for X-ray type transforms along geodesics and related problems for determining the metric tensor from boundary measurements.

Some of my work describes the long-time or far field behavior, including existence, of waves on curved space-times. Physically these arise in general relativity, including electromagnetic waves on a curved background. The microlocal approach to analysis on these spaces has made breakthroughs possible on linear and non-linear problems on asymptotically hyperbolic (AH) spaces as well as Kerr-de Sitter (KdS) space (rotating black holes in a cosmological spacetime), culminating in the proof of the stability of slowly rotating KdS spaces with Peter Hintz. More recently, with Dietrich Hafner and Peter Hintz, I extended some of these tools to the vanishing cosmological constant case (Minkowski, Kerr). Ongoing work aims to extend these tools to further spaces, such as perturbations of Kerr spacetimes, and also to study other equations on cosmological spacetimes. Other projects study basic objects in quantum field theory, in particular the Feynman propagator.

Another main area of my interest is inverse problems, where, together with Gunther Uhlmann, I introduced new tools for the spatially localized inversion of the geodesic X-ray transform, and with Plamen Stefanov and Gunther Uhlmann we extended this to the boundary rigidity problem, namely determining a Riemannian metric on a manifold with boundary from the length of geodesic segments connecting boundary points. Ongoing work involves extensions of this to anisotropic elasticity which plays an important role in the interior of the Earth. Another project with Yiran Wang studies the light ray transform with potential applications to imaging by the cosmic background radiation.
