PhD, The University of Chicago

Michael Maltenfort received his PhD from the University of Chicago in 1997. Following graduation, he was a Peace Corps volunteer in Kenya. He then returned to Chicago, where he briefly taught at DePaul University and Loyola University before joining the faculty at Truman College, where he taught from 2002 to 2013. He joined the faculty at Northwestern University as a Weinberg College Advisor in 2013.

Maltenfort’s research is in simple mathematics, including problems that are accessible to those whose background is limited to calculus.
