In 2009-10 and 2010-11 academic years, I was an undergraduate instructor for the Academic Excellence Workshops (AEW) at Cornell University. I co-taught weekly workshops on calculus 1 and general chemistry.

**Mentoring **

**Mentoring**

In Fall 2019, I hosted an undergraduate reading course MATH 4993: Directed Study on abstract algebra and mathematical logic.

In Spring 2018, I hosted an undergraduate reading course MATH 4993: Directed Study on group theory and chemistry. During the course, my student wrote an expository paper on the unsolvability of quintic equations as her Senior Project fulfilling the honors requirement.

I was a graduate student mentor for the UChicago REU in the summers of 2015 and 2016. Three students in my group, Mario Alegre, Pedro Juarez, and Hani Pajela, wrote a research paper titled "Statistics about polynomials over finite fields." Their paper is posted on the REU website.

I was a mentor for the Directed Reading Program (DRP) in Spring 2016 on analytic number theory.

In 2016, I received the

**Lawrence and Josephine Graves Prize**for excellent and effective teaching by graduate students from the Department of Mathematics, University of Chicago.
