Stephen DeBacker
As an undergraduate, Stephen DeBacker was inspired to pursue mathematics by renowned teaching masters Gerald Alexanderson and Paul Halmos. He survived graduate school thanks largely to the enthusiastic and effective mentoring of his thesis advisor, the legendary Paul J. Sally, Jr. He tries to pay forward some small part of his debt to these great teachers by working to inspire the next generation of scholars. Since arriving at the University of Michigan in 2002, he has served as director of the Michigan Math Circle, the Michigan Math and Science Scholars, and the Michigan Mathematics Undergraduate Program. He has also worked with elementary and secondary school teachers through the SESAME program (in both Chicago and Boston). In 2011 he was appointed as an Arthur F. Thurnau Professor, and in 2012 he was named Carnegie Foundation Professor of the Year for Michigan.

Sarah Koch
Sarah Koch is an Associate Professor of Mathematics at the University of Michigan in Ann Arbor. Her research is in the area of complex dynamical systems; she spends lots of time trying to understand the infinitely complicated structure of beautiful fractals that emerge in her work. She has two PhDs in Mathematics, one from the Université de Provence in Marseille, and one from Cornell University. She is proud to have received the Class of 1923 Memorial Teaching Award from the College of Literature, Sciences and the Arts at the University of Michigan in 2016. In addition to doing Math, she leads Math Circles in Wolverine Pathways, and coordinates the Math Mondays in Ypsi Program. She also enjoys teaching, working with students, running, and trying to improve her kickball skills.

Yunus Zeytuncu
Yunus E. Zeytuncu, Associate Professor of Mathematics. Dr. Zeytuncu earned his Ph.D. from the Ohio State University in 2010. He was a visiting assistant professor at Texas A&M University before joining the University of Michigan-Dearborn in 2013. As a research mathematician, he works in several complex variables and operator theory. In addition to the Math Corps at U(M), Dr. Zeytuncu also coordinates the REU Site in Mathematical Analysis and Applications, and the Maize and Blue Math Circle. In 2019, he received the Distinguished Teaching Award from the Michigan section of the Mathematical Association of America (MAA).
