I am an Assistant Adjunct Professor (postdoc) at
UCLA.
During the Spring semester 2017 I was a postdoctoral research associate at
MSRI in the
Analytic Number Theory program.
I received my PhD in 2016 from
UIUC under the direction of
Scott Ahlgren.
I completed my BS in mathematics with a minor in physics in 2011 at
BYU.
My research interests are in number theory.
I am particularly interested in arithmetic aspects of automorphic forms and their relation to (in no particular order) invariants of quadratic number fields, hyperbolic geodesics, class numbers,
Lfunctions, and additive number theory.
Here is my CV.

Teaching
In Fall 2018 I am teaching Math 205A [Analytic Number Theory] and Math 31B [Integration and Infinite Series]. See the teaching page for my previous teaching.
