I obtained my Ph.D. from the University of Michigan in 2014, and I am currently an assistant professor at the University of Oklahoma. My research interest lies in the analysis of PDE, using methods of harmonic analysis, calculus of variations and bifurcation theory. I have been studying rotating star solutions of the Euler-Poisson equations, the Vlasov-Poisson equations, and the inverse scattering theory of the Benjamin-Ono equation.

### Projects in Progress

I am working with Juhi Jang and Walter Strauss on equations of magentic rotating stars, and global continuation of steady rotating star solutions. A different project of my own aims at constructing rotating star solutions to the Einstein equations of general relativity. I am also working on the inverse scattering problem for the completely integrable Benjamin-Ono equation. Together with Peter Perry and Joel Klipfel, we are studying the inverse scattering transform for the Intermediately Long Wave equation.

### Teaching

In Fall 2018, I am teaching Math 2433 (Calculus and Analytic Geometry III).

In the past, I have taught different courses at Brown University, Indiana University and the University of Michigan. Courses include: precalculus, calculus (I, II, III), intro to ordinary differential equations, intro to partial differential equations, functional analysis, intro to probability and statistics, intro to stochastic processes, etc.
