In Summer 2015 and 2016, as Academic Coordinator, I designed the curriculum, recruited and supervised mentors, and gave lectures for the inaugural year of MathROOTS, a summer camp run by MIT PRIMES for promising high school students from underrepresented backgrounds interested in exploring creative topics in mathematics.
In Summer 2007-2010 and 2012-2017, I taught the US team to the International Mathematical Olympiad (IMO) at the Math Olympiad Program. In 2010, I was the Deputy Team Leader for the US team to the Romanian Masters in Mathematics. In 2011, I gave a guest lecture to the UK team to the IMO. In 2012-2013, I taught the Saudi Arabian teams to the IMO and International Physics Olympiad.
Notes for selected lectures at the Math Olympiad Program are below:
|Complex Numbers in Geometry|
|Smoothing, Fudging, and Ordering|
|Tricks in Trigonometry|
In 2010-2013, I co-authored a feature in Mathematics Magazine with the problems and solutions from the year's competition.
