**Research Summary**

I use techniques from Fourier analysis to study partial differential
equations.

(I also use partial differential equations as an excuse to do Fourier
analysis!)

My current projects involve linear dispersive estimates for
the Schrödinger,

wave and/or Dirac equations with a short-range potential, plus some more

classical Fourier Transform bounds.

The **14 ^{th} Ohio River Analysis Meeting** will take place March 29-30, 2025 at the University of Cincinnati!

Homepages for previous meetings: 2024 2023, 2022, 2021, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012, 2011.

These slides from some of my past talks
discuss specific problems and results.

The work is currently supported by the Simons Foundation under
grant #635369.
