Non-academic things I did in undergrad

I was a codirector of the MIT Video Game Orchestra in my senior year, and I sang with the MIT Asymptones and played in the MIT Symphony Orchestra during my first year at MIT. Music performance is important to me, but I am still thinking about how best to explore it going forward.

I was also an admin for the MIT Educational Studies Program; in 2019, I codirected MIT Splash, a weekend-long educational program for thousands of high school students. Other than that, I also took on various officer positions in HMMT and was a member of the Council for Math Majors.

Contest math problems

I've written a few problems for the HMMT competition; here are a few that I particularly like. (All of the past problems and solutions can be found on the HMMT site.)

  • HMMT February 2019 G8: In triangle ABC with AB < AC, let H be the orthocenter and O be the circumcenter. Given that the midpoint of OH lies on BC, BC=1, and the perimeter of ABC is 6, find the area of ABC.

  • HMMT February 2020 C3: Each unit square of a square grid is colored either red, green, or blue. Over all possible colorings of the grid, what is the maximum possible number of L-trominos that contain exactly one square of each color? (L-trominos are made up of three unit squares sharing a corner.)

  • HMMO 2020 T5: The classrooms at MIT are each identified with a positive integer (with no leading zeroes). One day, as President Reif walks down the Infinite Corridor, he notices that a digit zero on a room sign has fallen off. Let N be the original number of the room, and let M be the room number as shown on the sign. The smallest interval containing all possible values of M/N can be expressed as [a/b, c/d) where a,b,c,d are positive integers with gcd(a,b) = gcd(c,d) = 1. Compute 1000a + 100b + 10c + d.

Music

  • The MIT Video Game Orchestra has a YouTube channel with some of our past performances. One of my favorite arrangements is this medley of tracks from Paper Mario: The Thousand-Year Door -- expect some of my others to be posted soon too!

  • Our final project of 21M.303, Writing in Tonal Forms I, was to compose a minuet and trio for string quartet. You can find the score for my composition here, as well as a recording of it performed by the Worcester Chamber Music Society.

  • If you want to hear me play some chamber music with friends, feel free to check out these recital recordings from May 2022 (music composed by group members!) or December 2021. I am kind of rusty but the pieces are good!

My LaTeX style package

If you'd like your LaTeX document to look like the ones that I make, feel free to try using my style package! Including this file in your project and starting a document with "\usepackage{lindrew}" will import all of the shortcuts / formatting that I use. For a sample document and some answers to FAQs, please take a look at this Overleaf project.
