My cv.
I am an assistant professor of mathematics at Stony Brook University, with research interests in probability and analytic number theory. Previously I have been a postdoctoral fellow at the Institute for Advanced Study, Princeton, and a member of a research team led by Ben Green at the Mathematical Institute, Oxford and DPMMS, Cambridge. I completed my PhD in Mathematics at Stanford University in 2012 under the supervision of K. Soundararajan. I have also completed a masters degree in computer science at Stanford, with an emphasis in algorithms.
Analysis seminar:
Together with Chris Bishop and Raanan Schul, I am organizing the Stony Brook Analysis Seminar. Further information is available here.
Teaching:
In Fall of 2017 I am teaching Math 320: Introduction to Analysis.
In Spring of 2017 I taught Topics in Probability. Slides from the course are available here.
Areas of research interest:
 Probability, discrete mathematics, analytic number theory
Specific research projects:

Several years ago I solved an old problem of ErdÅ‘s by showing that the least modulus of a distinct covering system of congruences cannot be arbitrarily large. Here are talks by Ben Green, and myself discussing the solution. I have an ongoing research project with Pace Nielsen at BYU studying covering systems.
 A number of years ago Persi Diaconis tricked me into studying a random walk on a group, and I have been doing so from time to time ever since. I am especially interested in the cutoff phenomenon, in which a Markov chain transitions to stationarity in a narrow window about its mixing time. These papers use (new) integral formulae for the characters of the symmetric and (with Yunjiang Jiang) orthogonal groups. This preprint with Persi solves an old problem about the mixing time of coordinates in finite nilpotent groups.
 I have studied several distribution problems in analytic number theory, including the
distribution
and extreme values of Lfunctions, and the distribution of shapes of fixed torsion ideal classes in imaginary quadratic fields. In a recent preprint, I partially generalize the Shintani zeta function to an object giving spectral information about the distribution of the shapes of cubic orders. This is part of an ongoing project with Frank Thorne at USC and Takashi Taniguchi at Kobe University.

An illustration of Leon Green's Theorem.
The right figure is an orbit on the Heisenberg nilmanifold and the left is the projected orbit on the abelianization. Green's Theorem states that the first orbit is asymptotically equidistributed if and only if the second one is.

Older teaching material:
 At Cambridge I gave a Part III course in analytic number theory. Topics included the prime number theorem in arithmetic progressions, Linnik's theorem on the least prime in an arithmetic progression, and Selberg's theorem on the distribution of log zeta on the halfline.

At Stanford I was TA for the 3term honors multivariable calculus sequence. Handouts from my sections are available
here.
