Teaching MATH 165 and MATH 265 in Fall 2019

Steve Butler is an Associate Professor and the Barbara J. Janson Professor in the Department of Mathematics at Iowa State University. Prior to coming to Iowa State he did a three year NSF PostDoc under the supervision of Benny Sudakov at UCLA. Before that he earned his doctorate degree in mathematics at UC San Diego under the supervision of Fan Chung. In addition he has worked extensively with Ron Graham.

His primary mathematical interests are spectral graph theory, enumerative combinatorics, mathematics of juggling, discrete geometry, and generally mathematics of fun things. Among other things, he can do eight perfect faro shuffles in a row, and is willing to teach this to anyone who stops by his office.

Since Fall of 2018 Steve has been the calculus coordinator for Iowa State University. More information about what happens in the calculus class can be found on the following sites:,, and
