Ken Ono

Ken Ono (born March 20, 1968) is an American mathematician who studies number theory. Formerly the STEM Advisor to the Provost and the Marvin Rosenblum Professor of Mathematics at the University of Virginia, he now works in artificial intelligence at Axiom Math in Palo Alto, California.

Early life and education Ono was born on March 20, 1968, in Philadelphia, Pennsylvania. He is the son of mathematician Takashi Ono, who emigrated from Japan to the United States after World War II. Ono was born in the United States as his father returned to the United States from the University of British Columbia in Canada for a position at the University of Pennsylvania.

In the 1980s, Ono attended Towson High School, but dropped out. He later enrolled at the University of Chicago without a high school diploma. There he raced bicycles, and he was a member of the Pepsi–Miyata Cycling Team.

He received his BA from the University of Chicago in 1989, where he was a member of the Psi Upsilon fraternity.

He is the brother of Santa Ono, a professor of immunology and former academic administrator.

Career Ono worked as an instructor at Woodbury University from 1991 to 1993, as a visiting assistant professor at the University of Georgia from 1993 to 1994, and as a visiting assistant professor at the University of Illinois Urbana-Champaign from 1994 to 1995. to research the application of artificial intelligence to fundamental mathematics.

Research In 2000, Ono derived a theory of Ramanujan's congruences for the partition function with all prime moduli greater than 3. His paper was published in the Annals of Mathematics. In a joint work with Jan Bruinier, Ono discovered a finite algebraic formula for computing partition numbers.

In 2014, a joint paper by Michael J. Griffin, Ono, and S. Ole Warnaar provided a framework for the Rogers–Ramanujan identities and their arithmetic properties, solving a long-standing mystery stemming from the work of Ramanujan. The findings yield new formulas for algebraic numbers. Their work was ranked 15th among the top 100 stories of 2014 in science by Discover magazine.

In a 2015 joint paper co-authored with John Duncan and Michael Griffin, Ono helped prove the umbral moonshine conjecture. This conjecture was formulated by Miranda Cheng, John Duncan, and Jeff Harvey, and is a generalization of the monstrous moonshine conjecture proved by Richard Borcherds. However, the Riemann hypothesis remains unsolved. Their work also establishes the Gaussian Unitary Ensemble random matrix condition in derivative aspect for the derivatives of the Riemann Xi function.

In 2024, he published (co-authored with William Craig and Jan-Willem van Ittersum) a paper which proves a new, unexpected way to identify prime numbers using the properties of integer partitions. In 2025 he was nominated for the Cozzarelli Prize.

Beginning in 2016, Ono has used mathematical analysis and modeling to advise elite competitive swimmers, including participants in the 2020 and 2024 Olympics.

Media Ono wrote, with Amir Aczel as coauthor, an autobiography, emphasizing the inspiration he gained from Ramanujan's mathematical research.

Ono was an Associate Producer and the mathematical consultant for the movie The Man Who Knew Infinity, which starred Jeremy Irons and Dev Patel, based on Ramanujan's biography written by Robert Kanigel. He is on the Board of Directors of the Infinity Arts Foundation.

Personal life From 2012 to 2014, Ono has competed in World Triathlon Cross Championships events, representing the United States.
