Ken Ono

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 is the Asa Griggs Candler Professor of Mathematics at Emory University. Ono's contributions include several monographs and over 150 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 2012 he made world news for his work proving the last open conjectures contained in Ramanujan's enigmatic death-bed letter to G. H. Hardy.
