Board of Directors

Ali Cy

President

Ali is a high school senior at Phillips Academy Andover. She was an Honorable Mention for the 2020 USAJMO, and was on the 2020 USA European Girls' Math Olympiad team, at which she got a silver medal. She started doing math contests seriously in seventh grade. While participating in math contests, she saw the way in which girls were isolated in math and how that helped lead to the under-representation of girls at contests. She founded Athemath in order to help math girls connect to each other. Other than math, she enjoys playing the piano and programming.

Andrew Wu

Vice President

Andrew Wu is a rising junior at Yale University, living in the DC metropolitan area. He works as the head problem editor for the Yale-run competitions MMATHS and Girls in Math. In high school he qualified for USA(J)MO thrice, and published two papers in Euclidean geometry. Outside of math, Andrew loves playing piano — classical, pop, musical theatre, anything — and he’s passionate about educational equity, good writing, and graphic design.

Evan Chen

Director

Evan Chen (v_Enhance) is a math PhD student at MIT. He is one of the coaches of the USA IMO team, serving as a coordinator for the team selection tests and the assistant academic director at MOP. He is an editor-in-chief for the USA(J)MO editorial board and the author of the textbook Euclidean Geometry in Mathematical Olympiads. As a high school student, Evan was an IMO gold medalist and winner of the 2014 USAMO (which he took from 12:30am to 5am in Taiwan). Outside of math and teaching, Evan enjoys playing competitive Hanabi and entertaining students on Twitch.
