Kyle Petersen received his AB from Washington University in St. Louis and his PhD from Brandeis University in 2006 under the direction of Ira Gessel. He spent three years at the University of Michigan before joining the faculty at DePaul in 2009. His research interests include all aspects of Enumerative, Algebraic, and Topological Combinatorics. 

Apart from his research, Petersen has been involved with the Academy of Inquiry-Based Learning, a community which seeks to promote a more student-centered approach to teaching.
