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.
