Dijen K. Ray-Chaudhuri

January 30, 2023

Dwijendra Kumar Ray-Chaudhuri (born November 1, 1933) is a professor emeritus at Ohio State University. He and his student R. M. Wilson together solved Kirkman's schoolgirl problem in 1968 [1] which contributed to developments in design theory.

He received his M.Sc. (1956) in mathematics from the famous Rajabazar Science College, University of Calcutta and Ph.D. in combinatorics (1959) from University of North Carolina at Chapel Hill. He served as consultant at Cornell Medicine and Sloan Kettering, a professor and chairman of the Department of Mathematics at Ohio State University, as well as a visiting professor of University of Göttingen and University of Erlangen in Germany, University of London, and Tata Institute of Fundamental Research in Mumbai.

He is best known for his work in design theory and the theory of error-correcting codes, in which the class of BCH codes is partly named after him and his Ph.D. advisor Bose.[2] Ray-Chaudhuri is the recipient of the Euler Medal by the Institute of Combinatorics and its Applications for his career contributions to combinatorics. In 2000, a festschrift appeared on the occasion of his 65th birthday.[3] In 2012 he became a fellow of the American Mathematical Society.[4]
