My primary area of research is harmonic analysis and its applications to elliptic partial differential equations with non-smooth coefficients. I also have a research interest in cryptography, in particular lattice based cryptography and the NTRU public key cryptosystem.

My primary area of research is harmonic analysis and its applications to elliptic partial differential equations with non-smooth coefficients.

In harmonic analysis, I have specific interests in multiparameter Fourier analysis: differentiation and covering lemmas, multi-linear operators, and singular integrals. My research in elliptic pde is primarily in the area of boundary value problems associated to divergence and non-divergence second and higher order operators whose coefficients lack smoothness.

I teach a wide range of courses at the undergraduate level. The upper division courses are usually analysis, partial differential equations, probability, statistics, functional analysis and cryptography. At the graduate level, I teach real and complex analysis, PDE, probability, and topics courses in these areas.
