Tom Halverson is DeWitt Wallace Professor and Chair of the Mathematics, Statistics, and Computer Science Department at Macalester College. Tom has been teaching at Macalester College since 1993.

He teaches courses in linear and abstract algebra, discrete mathematics, computational linear algebra, calculus (applied, single, and multivariable), and topology. His research interests are in algebra and combinatorics, specifically in combinatorial representation theory, where he uses tools from combinatorics to study matrix representations of algebraic structures. He earned his MA and PhD from the University of Wisconsin-Madison (1993) and his BA from Saint Olaf College (1986). He has spent sabbaticals at the Institute for Advanced Study (Princeton, 1999) and the Mathematical Sciences Research Institute (Berkeley, 2008).

In March 2016, George Hart installed a sculpture, called *Ambagesque *(from the Latin word for “tangle”) in Macalester’s Olin-Rice Smail Gallery. The sculpture has icosahedral (A5) symmetry.
