Computer Science: Faculty


*Department Chair

Darrah Chavey (221 Science Center, 363–2220; 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 Darrah Chaveyteams 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 UpdateSteven 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. From 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 bicycle safety education. In 2009-2010, he did sabbatical work in Oaxaca, Mexico.
