Research Interests
Fourier analysis and its applications to the study of
partial differential equations.
My current project is to prove linear dispersive estimates for
the Schrödinger and wave equations in a variety of settings.
These slides from some of my recent talks
discuss specific problems and results.
This year I am also organizing the
Analysis and
PDE Seminar at Johns Hopkins.
