From Wikipedia, the free encyclopedia
Mark Norman Ellingham is a professor of mathematics at Vanderbilt University whose research concerns graph theory.[1] With Joseph D. Horton, he is the discoverer and namesake of the Ellingham–Horton graphs, two cubic 3-vertex-connected bipartite graphs that have no Hamiltonian cycle.[2]
Ellingham earned his Ph.D. in 1986 from the University of Waterloo under the supervision of Lawrence Bruce Richmond.[3] In 2012, he became one of the inaugural fellows of the American Mathematical Society.[4][5]
