Coullard graduated in 1980 from Lake Superior State University,^[1][2] and earned her Ph.D. in 1985 from Northwestern University. Her dissertation, Minors of 3-Connected Matroids and Adjoints of Binary Matroids, concerned matroid theory and was supervised by Robert E. Bixby.^[3]

She taught at Purdue University and the University of Waterloo^[4] before returning to Northwestern as a faculty member in 1990,^[2] and retired as a mathematics professor from Lake Superior State University in 2018.^[5] She has also visited the University of Bonn as a Humboldt Fellow.^[4]

Coullard was a Charles Deering McCormick Professor of Teaching Excellence at Northwestern University from 1996 to 1999.^[1][2] In 2003, the Lake Superior State University Alumni Association gave her their annual Kenneth J. Shouldice Achievement Award.^[1]
