He did his undergraduate studies at Earlham College, graduating in 1975.^[1] He completed his Ph.D. in 1980 from Ohio State University, under the supervision of Henry Hatfield Glover, with a dissertation proving an analogue of Kuratowski's theorem for the projective plane.^[4] He took a position at the University of Vermont in 1982, joining fellow graph theorist and Ohio State graduate Jeff Dinitz, after previously working as an instructor at the University of Kansas.^[1][3] He died of cancer on February 18, 2015, in Burlington, Vermont.^[1]
