Biography

Michael Maltenfort is a Weinberg College Adviser and Assistant Professor of Instruction in Mathematics. He earned his bachelor's degree in mathematics from Cornell University, and his doctorate, also in mathematics, from the University of Chicago. 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 loves the mathematical aspects of the Rubik’s Cube and related puzzles, and he also uses his mathematical talent when calling square dances: he has been an enthusiastic square dancer for decades and has been a square dance caller since 2002. Since 2020 he has taught a Weinberg College Seminar that looks at diversity, equity, and inclusion in mathematics and beyond.
