My name is Matthew Liu, and I am an incoming Honours Mathematics Student at the University of Waterloo. Previously, I was an International Baccalaureate (IB) Student at Cameron Heights Collegiate Institute from 2021 to 2025.

I have been a speedcuber (of the Rubik’s Cube) since 2018. I have been ranked in Canada's Top 50 list in two events (7×7 Cube [#47] and 3×3 Fewest Moves [#41]), and in the Top 100 in four events (5×5 Cube [#67], 6×6 Cube [#51], 7×7 Cube [#47], and 3×3 Fewest Moves [#41]). I have participated in the 2019 Canadian Championship, the 2022 North American Championship, and the 2023 US Nationals (the largest cubing competition ever organized at the time). I will also be participating in the 2025 Canadian Championship in Montreal at the end of July. I placed 11th at the FMC Canada 2025, the Canadian Championship for the 3×3 Fewest Moves event. I am a sales representative for Cubing Out Loud, the largest Canadian-owned speedcubing store.

In 2023, I was accepted to PACT (Program in Algorithmic and Combinatorial Learning), a computer science and discrete mathematics summer program at Princeton University under Dr. Rajiv Gandhi, PhD.

In 2024, I was accepted to Harvard's 7-Week Summer Program and took the "Intensive Introduction to Computer Science" course,  CSCI S-111, under Dr. David G. Sullivan, PhD. I received an A Grade, the highest possible grade in the course.
