U.S. Team Takes First Place at International Mathematical Olympiad US Team at International Mathematical Olympiad

The six-person team representing the United States took first place at the 56th International Mathematical Olympiad (IMO), the world championship mathematics competition for high school students. More than 100 countries sent their national teams to this year’s competition in Chiang Mai, Thailand, from July 4 to 16. The last time the U.S. team took first place was in 1994.

“This historic result reflects an enormous amount of work by students, families, teachers, and coaches, as well as an extensive national infrastructure for the cultivation of extraordinary mathematical talent,” said Po-Shen Loh, an associate professor in the department of mathematical sciences at Carnegie Mellon and the national coach of the U.S. IMO team. “We thank the members of Team USA for providing an inspiration for all.”

The members of the U.S. team were Ryan Alweiss, Allen Liu, Yang Liu, Shyam Narayanan, and David Stoner, all of whom were awarded gold medals, and Michael Kural, who earned a silver medal, just one point away from the gold. IMO scores are based on the number of points scored by individual team members on six problems. The problems are taken in sets of three in 4.5 hour sessions over two days. The U.S. team’s combined score of 185 edged out the Chinese team’s score of 181 and the Republic of Korea’s third-place score of 161.

Participants on the U.S. team were selected through a series of competitions organized by the Mathematical Association of America (MAA), culminating with the USA Mathematical Olympiad. The six team members joined 48 of their peers at Carnegie Mellon this past June for three weeks of immersion in problem solving at MAA’s Mathematical Olympiad Summer Program, a summer training camp directed by Loh.
