He has received two notable awards from the Mathematical Association of America: the Allendoerfer Prize for expository writing in 1990 and being named a Distinguished Teacher of Mathematics in 2001. His research interests include algebraic number theory, hypergeometric series, differential equations, and the history of mathematics. His book Special Functions with co-authors Richard Askey and George Andrews was published in 1999. In 1997 he taught a first-year seminar on Indian mythology.

Amy Shell-Gellasch (214 Science Center,363-2566; shella@beloit.edu) Visiting Assistant Professor of Mathematics. B.S. Ed. (math and physics) University of Michigan, M.A. (math) Oakland University, D.A. University of Illinois at Chicago (2000). Amy’s thesis was an historical piece on mathematician Mina Rees. She was named an R. L. Moore Project NeXT Fellow in 2000 and spent three years as a post-doctorate at the United States Military Academy where she conducted historical research with Fred Rickey. Her focus is the History of Mathematics and Its Uses in Teaching. For example, her most recent publication is the MAA Notes volume Hands On History which provides ways for teachers to make and use historical models in the mathematics classroom.She is very involved in the MAA and the HOM SIGMAA. She currently Chairs the MAA Committee on SIGMAAs. She co-founded and is current Programs Chair of the HOM SIGMMA and founded the HOM SIGMAA Student Paper contest. She has organized numerous meetings and sessions to include the 2009 JMM MAA short course, Exploring the Great Books of Mathematics.
