## Faculty & Staff

### Catherine E. Cavagnaro

#### Professor of Mathematics

Catherine Cavagnaro holds a B.S. from Santa Clara University and a Ph.D. from University of Illinois at Urbana-Champaign. Geometric topology and combinatorial group theory served as the basis for her thesis. She enjoys problems from a variety of other fields including statistics, cryptology as well as differential equations and aerodynamics.

### Hoss Craft

#### Visiting Assistant Professor of Psychology and Mathematics

Warren Craft received both his B.A. and Ph.D. from Vanderbilt University and has taught at Sewanee in both Mathematics and Psychology since 1998. His current research interests focus on the geometrical information available to the visual system in retinal images of our three-dimensional environment. Other academic interests include the cognitive and neurophysiological bases for depression, mindfulness-based cognitive therapy (MBCT), consciousness studies, and computer programming (most recently becoming obsessed with Perl).

### Fred Croom

#### Professor of Mathematics

Fred Croom received his B. S. and Ph. D. in mathematics from the University of North Carolina at Chapel Hill. He is the author of two textbooks, one on general topology and the other on algebraic topology. His current research interest is in the early history of general topology, especially the contributions of Paul Urysohn in the 1920s.

### Joel L. Cunningham

#### Professor of Mathematics

Joel Cunningham received a B.A. from the University of Chattanooga and M.A. and Ph.D. from the University of Oregon. His research has been in commutative ring theory and algebraic number theory. He has been Sewanee’s vice chancellor since 2000 and will return to full-time teaching after a sabbatical leave in 2010-11.

### Douglas J. Drinen

#### Chair and Associate Professor of Mathematics

Doug Drinen has a B.A. from Trinity University in Texas and a Ph.D. from Arizona State University. After a two year post-doc at Dartmouth College, he came to Sewanee in 2001. He greatly enjoys teaching across the entire undergraduate mathematics curriculum. During his time at Sewanee, his research interests have shifted from functional analysis to probability, graph theory, economics, and any other area in which he can find problems to work on with students and colleagues.

### Chris Parrish

#### Professor of Mathematics

Chris Parrish received his M.A. and Ph.D. degrees from the University of California at San Diego, and taught mathematics for twelve years at Universidad Simón Bolívar in Caracas, Venezuela. Recently he has taught courses in differential equations, differential geometry, and calculus on manifolds in which students reinforce their understanding of abstract mathematics by interacting with the modeling and graphics visualization capabilities of a sophisticated computer algebra system.

### Emily E. Puckette

#### Professor of Mathematics

Emily Puckette holds a B.A. from Smith College and an M.A. and Ph.D. from Duke University. She began her career in mathematics by teaching and training teachers as a volunteer in the Peace Corps in Gabon in Central Africa. Her mathematical fields of interest are probability and analysis, and her pedagogical focus is engaging students in mathematics through active-learning techniques in the classroom.

### Matthew Rudd

#### Associate Professor of Mathematics

After graduating from Wake Forest University, Matthew Rudd moved to Chicago, where he earned an M.S. at the University of Chicago, had a stint in the horn section of a soul band, and worked as a computer programmer. Unable to resist mathematics any longer, he returned to studying partial differential equations and completed a Ph.D. at the University of Utah. He came to Sewanee after stops at the Universities of Texas and Idaho, and he enjoys working with students in class and on research projects.
