Jeff Kahn

Jeffry Ned Kahn is a professor of mathematics at Rutgers University whose work is chiefly in combinatorics. He received his doctorate from Ohio State University in 1979, writing his dissertation under Dijen K. Ray-Chaudhuri. In 1980 he showed the importance of the bundle theorem for ovoidal Mobius planes, and in 1993, together with Gil Kalai, he disproved Borsuk's conjecture. He received the Polya Prize of the Society for Industrial and Applied Mathematics in 1996 and was an invited speaker at the 1994 International Congress of Mathematicians in Zurich. In 2012 he shared the Fulkerson Prize with Anders Johansson and Van H. Vu for determining the edge density threshold above which a random graph can be covered by disjoint copies of a given smaller graph, and he became a fellow of the American Mathematical Society.
