Seminars

Thesis and Expository Notes

  • On the Global Behavior of Wave Maps.
    My PhD thesis from the University of Chicago.
  • Nonlinear Wave Equations.
    These notes give a brief introduction to nonlinear wave equations. They were written during my second year at the University of Chicago as part of my topics examination and comprise part of my own introduction to the subject. They cover the local well-posedness theory for semilinear wave equations with smooth data as well as Strichartz estimates with applications including small data global existence and scattering for wave equations with power type nonlinearities.
