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.

The program was featured on the MIT Homepage and covered by MIT News and Notices of the AMS.

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:
