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 equation in a variety of settings,
with an eye toward understanding the dynamics of NLS evolution
near standing wave solutions.
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.
