Seminars and Conferences

I am currently one of the organizers of the UC Irvine Number Theory Seminar. Here is a link to our upcoming and reccent talks .

I am an organizer of Southern California Number Theory Day at UC Irvine. Our next meeting will be in the fall of 2019.

I was an organizer for the Conference on Open Questions in Cryptography and Number Theory in honor of Alice Silverberg's 60th Birthday. The conference took place at UC Irvine September 17-21, 2018.

In 2013-14 I helped organize the Yale Number Theory Seminar. In Fall 2014 and Spring 2015 I helped organize the Yale Algebra and Number Theory Seminar. I also helped to organize the Algebraic and Tropical Geometry meeting BATMOBYLE in Fall 2014 andSpring 2015.

Undergraduate Research

I would highly encourage undergraduates to apply for summer research programs. Here are a few programs that I am familiar with and would definitely recommend.

If you are a current UCI undergraduate looking for opportunities to do research on campus, check out the UROP website. For opportunities to do research over the summer, see SURP.

UCI has several programs to promote diversity in research on campus. SURF is a program where non-UCI undegraduates spend the summer doing research at UCI. The Competitive Edge summer program is for incoming UCI graduate students looking to get an early start on research.

If you have questions about any of these programs feel free to send me an email.


I am also interested in other types of mathematical outreach. I have given talks at the UCI Math Circle, the Southern California State MathCounts competition, the Hunter College High School Science Research Seminar, the UCI Anteater Mathematics Club, the Yale Undergraduate Math Society, the Family Fridays program at the Museum of Math, the Math Mornings program at Yale, and at a math circle on Long Island. Here is a link to the video for my Math Mornings talk.

In graduate school I taught a 10-hour minicourse called A Mathematical Look at Some Popular Games. In this course we explored some of the math behind Tic-Tac-Toe, Sudoku, SET, and several other games.


I really enjoy trivia and have appeared on four game shows. In November of 2009 I appeared on Who Wants to be a Millionaire, in Septeber of 2013 I was on The Million Second Quiz, in May of 2015 I was on Let's Ask America, and in May 2016 I was on 500 Questions. Yale News wrote an article about my adventures in the game show universe.

My favorite numbers are 20,213, (π^2)/6, and 52,416,000.
