 *Department Chair

Bruce Atwood

Bruce Atwood Adjunct Associate Professor.

(214 Sanger Science Center, 363–2474;

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 University. An avid user of Mathematica, he is particularly interested in wavelets and in the uses of technology in teaching. In Fall 2012, he taught a first-year seminar on “Size and Structure.” In summer 2013, he mentored Lingzhi Meng ’14 in a Beloit College Sanger Summer Scholars Project on time series forecasting by wavelets.


Paul Campbell

Paul Campbell Professor.

(217 Sanger Science Center, 363–2007;

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 returned there for a visit in summer 2013.


Darrah P. Chavey Specializes in Ethnomathematics, Geometry, and Group Theory. For more details, see his listing under Computer Science


David Ellis Professor.Dave Ellis

(218 Sanger Science Center, 363–2369;

Ph.D. (topology) University of California–Berkeley.

Dave was chair of the department from 1994–1999 and 2004–2006. His special interests include the topology of dynamical systems, a topic on which he is preparing a book. He was on sabbatical 2013–2014. His book Automorphisms and Equivalence Relations in Topological Dynamics, co-authored with his father, appeared summer 2013.



Erin MunErin Munroro Assistant Professor. 

(220 Sanger Science Center, 363–2566;

B.A. Connecticut College, M.S. and Ph.D. (mathematics) Tufts University.

Within the interdisciplinary field of computational neuroscience, Erin studies very fast oscillations (VFOs, >80 Hz) their mechanisms and their role in neural circuits using multi-scale models and data analysis. These oscillations are found in the neocortex and hippocampus, and are seen during sleep, neocortical processing, and in epileptic tissue. Much of her work involves studying VFOs produced by a network of axons connected by gap junctions (an axonal plexus). Currently, Erin is analyzing data from auditory cortex to study sleep, auditory processing, and tinnitus. She plans to use the findings to model the implications of VFOs in the neocortex. Since neural populations generating VFOs send a strong signal to downstream populations, she hypothesizes that VFOs may play an important role in neural communication and plasticity.


Ranjan Roy* Professor and Chair.Ranjan Roy

(216 ScienceCenter, 363–2348;

B.S. and M.S. Indian Institute of Technology, Ph.D. (complex analysis) State University of New York at StonyBrook. 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 2013, he mentored Jianing Xu ’13 in a Beloit College Sanger Summer Scholars Project on examples of the modularity theorem.
