Ken Ono (born 1968) is an American mathematician who specializes in number theory, especially in integer partitions, modular forms, and the fields of interest to Srinivasa Ramanujan. He was the Manasse Professor of Letters and Science and the Hilldale Professor of Mathematics at the University of Wisconsin–Madison.
Ono's contributions include several monographs and over 140 research and popular articles in number theory, combinatorics, and algebra. He is considered to be an expert in the theory of integer partitions and modular forms. In 2000 he 'greatly' expanded Ramanujan's theory of partition congruences, and in work with Kathrin Bringmann he has made important contributions to the theory of Maass forms, functions which include Ramanujan's mock theta functions as examples. In 2007 Don Zagier gave a Seminar Bourbaki address on the work of Bringmann, Ono, and Zwegers on the mock theta functions. The 2009 SASTRA Ramanujan Prize, awarded to a young mathematician under the age of 32, has been awarded to Kathrin Bringmann for this joint work with Ono. In 2012 Ono made world news for his work proving the last open conjectures contained in Ramanujan's enigmatic death-bed letter to G. H. Hardy.
Ono has received many awards for his research. In April 2000 he received the Presidential Career Award (PECASE) from Bill Clinton in a ceremony at the White House, and in June 2005 he received the National Science Foundation Director's Distinguished Teaching Scholar Award at the National Academy of Science. He has also won a Sloan Fellowship, a Packard Fellowship, and a Guggenheim Fellowship. In 2012 he became a fellow of the American Mathematical Society.
In the 1980s he attended Towson High School. He left high school early to attend the University of Chicago and race bicycles. He was a member of the Pepsi-Miyata Cycling Team. In recent years, Ono has resumed athletic training as a runner, swimmer and cyclist; since 2012, he has competed in triathlons as a member of Team USA.
In 2011 Ono gave a TED talk. 
He stars in the 2013 docudrama "The genius of Srinivasa Ramanujan".
Ken Ono now lives in Atlanta GA with his wife Erika, daughter Aspen, and son Sage.
