Jeff Kahn
Jeffry Ned Kahn is a professor of mathematics at
Rutgers University notable for his work in
combinatorics .

Education
Kahn received his Ph.D. from
Ohio State University in 1979 after completing his dissertation under his advisor
Dijen K. Ray-Chaudhuri .^{
[1]}

Research
In 1980 he showed the importance of the
bundle theorem for ovoidal
Möbius planes .^{
[2]} In 1993, together with
Gil Kalai , he disproved
Borsuk's conjecture .^{
[3]} In 1996 he was awarded the
Pólya Prize (SIAM) .

Awards and honors
He was an invited speaker at the 1994
International Congress of Mathematicians in Zurich.^{[

In 2012, he was awarded the
Fulkerson Prize (jointly with Anders Johansson and
Van H. Vu ) for determining the threshold of edge density above which a
random graph can be covered by disjoint copies of a given smaller graph.^{

[5]} Also in 2012, he became a fellow of the
American Mathematical Society .^{
