Bruce Atwood

Bruce Atwood (214 Science Center, 363–2474; Adjunct Assistant Professor. B.S. (chemical engineering) Stanford University, M.A., Ph.D. (chemical engineering) Princeton University, M.M. (management)  Northwestern University, M.S. (pure mathematics) Northern Illinois University. Bruce previously taught mathematics at Rockford College.  An avid user of Mathematica, he is particularly interested in wavelets and in the uses of technology in teaching.  In summer 2011 he mentored Sijia Liang '12 in research on balancing a can on its edge.  This Fall he is teaching a first-year seminar on "Size and Structure."

Paul CampbellPaul Campbell (217 Science Center, 363–2007; Professor . B.S. (mathematics) University of Dayton, M.S. (algebra) and Ph.D. (mathematical logic) Cornell University. Paul was a Danforth Fellow, an Honorary Woodrow Wilson Fellow, and a National Science Foundation Fellow. He is editor-in-chief of The UMAP Journal of Undergraduate Mathematics and Its Applications and co-author of For All Practical Purposes (9th ed., 2013), an introductory college text in contemporary applied mathematics. He is interested in everything, but special interests include actuarial science, environmental modeling, probability and statistics, computer science, combinatorial games, and history of mathematics. In 1997-1998 and 2004-2005 he was in a probability and statistics group at the University of Augsburg, Germany.   He was on sabbatical leave 2011-2012.

Darrah ChaveyDarrah Chavey (221 Science Center, 363–2220; Associate Professor. B.A. University of Michigan–Flint, M.A. (mathematics), M.S. (computer science), and Ph.D. (geometry) University of Wisconsin–Madison. Darrah has published a series of papers on the geometry of tilings and  is the author of Drawing Pictures with One Line: Exploring Graph Theory (1983). For many years he coached the College's teams in the annual ACM Computer Programming Competition, including two teams that went to the international finals. Special interests include  the design and analysis of algorithms, software engineering,  parallel programming, geometry, and ethnomathematics. In summer 2012 he mentored research by Hugh Smith '13 on games on graphs (supported by Beloit College Trustee Jim Sanger) and a McNair Scholars Project (funded by the U.S> Department of Education TRIO program) with Mackenzie Endress '14 on game theoretic aspects of the influence of Super PACs in the 2012 Presidential election.  Web site:

Dave EllisDavid Ellis (218 Science Center, 363-2369; Professor. Ph.D. (topology) University of California—Berkeley. Dave was chair of the department from 1994 to 1999 and 2004-2006. Special interests include the topology of dynamical systems, a topic on which he is preparing a book.  He is chair of the department's weekly Mathematics Colloquium.


Ranjan RoyRanjan Roy* (216 Science Center, 363–2348; Professor and Chair. B.S. and M.S. Indian Institute of Technology, Ph.D. (complex analysis) State University of New York at Stony Brook. Ranjan was the College's Teacher of the Year in 1986 and again in 2000. 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, and his book Sources in the Development of Mathematics: Series and Products from the Fifteenth to the Twenty-First Century appeared in 2011.  In 1997 he taught a first-year seminar on Indian mythology.  In summer 2012, he mentored Zhitai Li '14 in a Sanger Summer Scholars Project on the development of modular functions, including devising diagrams for an upcoming continuation of Ranjan's book on sources in the development of mathematics.
