I am an assistant professor in the math department at Texas
A&M University. Before coming here, I was a Boas Assistant
Professor at Northwestern
University. I received my Ph.D. from Stanford University in 2010.
I was a student of Rafe
Mazzeo
and András
Vasy.

I am interested in partial differential equations generally and
geometric microlocal analysis more specifically. Here is my (likely
out-of-date) CV. I am supported by NSF grant DMS--1500646.

**Seminars**

**Teaching**

- I am not currently teaching.
- In Fall 2015, I taught Math 308 (a course on differential equations) and Math 460 (a course on general relativity).
- In Spring 2015, I taught Math 304, a course on linear algebra.
- In Fall 2014, I taught Math 221, a multivariable calculus course for science and math majors. The course was administered through eCampus (and so there is no accessible course website).
**Northwestern University**- In Autumn 2013 I taught Math 381: Fourier Series and Boundary Value Problems for ISP.
- I gave two lectures on the WKB approximation at theNorthwestern University undergraduate conference on "Quantization and Mathematics".
- In Winter 2012 I taught Math 360 MENU Applied Analysis. This is the second quarter of a two-quarter sequence and introduces students to ODEs with MATLAB. In Autumn 2011 I taught the first quarter of the sequence.
- In Autumn 2010 I taught Math 220 and in Winter 2011 I taught Math 224. These are the first and second quarters of single-variable calculus.

- At Stanford University, I was a teaching assistant for linear algebra and multivariable calculus, ordinary differential equations, and honors multivariable calculus. I was also the course assistant for graduate courses in functional analysis and harmonic analysis, and for advanced undergraduate courses in differential topology and Galois theory.

**Conference Organization**

- I am organizing (with Luc Hillairet and Jared Wunsch) a workshop on "Evolution equations on singular spaces" at CIRM in Luminy, France, to be held April 25--29, 2016.
- I was an organizer (with Valentino Tosatti, Ben Weinkove, Jared Wunsch, and Steve Zelditch) of the 73rd Midwest PDE Seminar, held at Northwestern University during the weekend of May 10-11, 2014.
- I also organized (with Igor Rodnianski, Gigliola Staffilani, and Jared Wunsch) a workshop on evolution equations in honor of Terence Tao at Northwestern University in May 2012.
- I was an organizer (with Emmanuel Schenck, András Vasy, Jared Wunsch, and Steve Zelditch) of the Microlocal Methods In Spectral and Scattering Theory workshop at Northwestern University in October 2011.
