Andrew Dykstra, Ph.D., Assistant Professor of Mathematics

Areas of Expertise: dynamical systems, symbolic dynamics and ergodic theory.
Andrew Dykstra earned his Ph.D. from the University of Maryland and a bachelor’s degree from Carleton College. More >>

Before joining the Hamilton faculty, Dykstra spent two years as the Yates Postdoctoral Fellow at Colorado State University.

Dykstra's research is in dynamical systems. He is especially interested in symbolic dynamics and ergodic theory.

Courtney Gibbons, Ph.D., Assistant Professor of Mathematics

Areas of Expertise: commutative algebra, homological algebra, and applied algebra.
Courtney Gibbons received her M.S. and Ph.D. from the University of Nebraska-Lincoln (2009, 2013), where she studied homological properties of modules over quadratic algebras. More >>

A Connecticut native, Gibbons graduated summa cum laude with a B.A. in mathematics from Colorado College (2006).

Gibbons' work appears in the Journal of Pure and Applied Algebra, and, soon, in the Journal of Commutative Algebra. She also codes for Macaulay 2, an open-source algebra software package.

Gibbons plans to include Hamilton students in her research agenda and to design algebra electives that blend classical theory and modern applications.

Robert Kantrowitz, Ph.D., Professor of Mathematics

Areas of Expertise: analysis and commutative Banach algebras.
Robert Kantrowitz, a 1982 graduate of Hamilton College, earned a master's and doctorate from Syracuse University. He returned to join the Hamilton faculty in 1990 and has served as Mathematics Department chair since 2010. More >>

His research is in analysis, with particular focus on Banach algebras, automatic continuity, and operator theory, and his teaching interests include analysis, linear algebra, and calculus.

Kantrowitz's latest article, "Series that converge absolutely but don't converge," appeared in The College Mathematics Journal.  His other recent work has focused on modeling projectile motion and on stochastic matrices. The article "Optimization of projectile motion in three dimensions" appeared in Canadian Applied Mathematics Quarterly, and "A fixed point approach to the steady state for stochastic matrices" is slated to appear in a forthcoming issue of Rocky Mountain Journal of Mathematics.

Tim Kelly, Ph.D, Associate Professor of Mathematics

Areas of Expertise: mathematical education; probability, statistics, stochastic processes, and pre-calculus; and probabilistic and statistical reasoning.
Kelly came to Hamilton in 1985 from the University of New Hampshire, where he also earned his Ph.D. in mathematical education.

Larry Knop, Ph.D., Professor of Mathematics Emeritus

Areas of Expertise: statistics, linear algebra, mathematical modeling, computer-augmented learning, and algebra.
Knop earned his Ph.D. from the University of Utah. reas of interest are mathematical modeling and improper integrals, and differential equations.

Chinthaka Kuruwita, Ph.D., Assistant Professor of Mathematics

Areas of Expertise: nonparametric density estimation, and quantile regression models.
Chinthaka Kuruwita received a bachelor's degree in statistics from the University of Colombo, Sri Lanka, and came to the U.S. to pursue graduate studies in 2005. More >>

Kuruwita earned a master's degree and Ph.D in mathematical sciences with a concentration in statistics from Clemson University.  His research is focused on new regression models. During his stay in the U.S. he was involved in developing a new modeling strategy to assess suicidal risk of adolescents in the U.S. that was published in Journal of Adolescent Health (2009).

Michelle LeMasurier, Ph.D., Associate Professor of Mathematics

Michelle LeMasurier received her Ph.D. from the University of Georgia and joined the Hamilton faculty in 2001.

Robert Redfield, Ph.D., Samuel F. Pratt Professor of Mathematics

Areas of Expertise: lattice-ordered fields, rings and groups, vector lattices, and ordered topolgical spaces.
Robert Redfield earned his Ph.D. from Simon Fraser University, Burnaby, B.C., Canada. More >>

Redfield's recent work has focused on functions on lattice-ordered rings and vector lattices. In March 2004, Redfield spoke on "Positive Derivations on archimedean lattice-ordered rings" at the Conference on Lattice-Ordered Groups and f-Rings at the University of Florida. In July 2004, he spoke on "Order bases in lattice-ordered algebraic structures" at the University of Mississippi and on "Wilson bases" at the University of Houston - Clear Lake. His latest paper, "Fields of quotients of lattice-ordered domains," written with Jingjing Ma, will be appearing soon in Algebra Universalis.

Joshua Wiscons, Ph.D., Visiting Assistant Professor of Mathematics

Joshua Wiscons rejoins Hamilton College as a visiting assistant professor of mathematics. More >>

After receiving his Ph.D. from the University of Colorado in 2011, Wiscons spent one year on the faculty of Hamilton College before moving to Münster, Germany, for a two year postdoc funded by a fellowship from the National Science Foundation. His research lies in the intersection of group theory and model theory. The former is roughly the study of symmetry; while, the latter is an area of mathematical logic. Equally passionate about education, Wiscons has been teaching mathematics at the college level for many years.
