[Bruce Atwood]Bruce Atwood (214 Science Center, 363–2348; Visiting 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 Campbell]Paul 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 Chavey]Darrah 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:

[Steven Huss-Lederman]Steven Huss-Lederman (219 Science Center, 363–2071; Associate Professor. B.S. (chemistry) University of Maryland, Ph.D. (chemical physics) California Institute of Technology. His thesis concerned algorithms for computer statistical models to understand vibration in molecules. From 1987 to 1995, he was co-principal investigator at the Supercomputing Research Center for projects on parallel algorithms for distributed memory computers. He is co-author of 3 books on a standard for computer message-passing and of 21 articles on parallel computer architecture, quantum molecular dynamics, and Strassen's algorithm for matrix multiplication. For 1995–2000 he was Associate Scientist and Faculty Associate in the Computer Sciences Dept. of the University of Wisconsin–Madison. His interdisciplinary interests include linking CS courses to other disciplines; technology, ethics and privacy; and bicycles safety education. In 2009-2010 he did sabbatical work in Oaxaca, Mexico.

[Rama]Rama Viswanathan (419 Science Center, 363-2273; Professor.  B.S. St. Xavier's College--Bombay University, M.S. Indian Institute of Technology, and Ph.D. (physical chemistry) University of Oregon. After performing research in chemistry at Northwestern University as a post-doctoral fellow, Rama joined Beloit College in 1983.  He was a visiting scientist at the IBM Almaden Research Center during 1986, and a visiting associate professor of chemistry at Northwestern University in 1989. Rama also served for three years as the College's Director of Academic Computing. Special interests in CS include scientific computation, parallel processing, high speed data acquisition, interfacing instruments to computers, and applications of wireless technology in Room Area Networks (RANs) using laptops, mobile devices, and PDAs. On his sabbatical leave in Fall 2003, Rama researched bioinformatics as a member of the  BEDROCK Consortium ( He is currently developing the Wallputer, an inexpensive solar-powered computer with dedicated client software that can also serve as an information kiosk, announcement display, or message board. He has developed and chairs the College's interdisciplinary program in Computational Visualization and Modeling (CVM).  He was on sabbatical leave Fall 2012.  Web site:
