Interests
My main mathematical interests are in applications of harmonic analysis to
partial differential equations and mathematical physics.
I am particularly interested in oscillatory and singular integrals and integral operators
that arise in the analysis of dispersive PDEs such as the Schrödinger, wave and Dirac equations.
Since September 2017 my work is partially supported by the Simons Foundation under grant #511825.
