## Faculty Fields

**Federico Ardila** investigates objects in algebra, geometry, topology and applications by understanding their underlying combinatorial structure.

**Sheldon Axler** works on functional analysis and complex analysis. He also always seems to be writing another book.

**David Bao** was trained in mathematical physics and later switched to differential geometry. He works on curvature-driven problems in Riemann-Finsler geometry.

**Matthias Beck** works in discrete & computational geometry and analytic number theory. He is particularly interested in problems and applications connected with lattice-point enumeration in polytopes.

**Henry Boateng** is an applied and interdisciplinary mathematician with interests in problems at the intersection of computational mathematics and the natural, physical and social sciences.

**Emily Clader's** research is at the intersection of algebraic geometry and mathematical physics. Specifically, she is interested in the moduli space of curves and new techniques for curve-counting that theoretical physics has inspired.

**Arek Goetz's** research interests include dynamical systems, symbolic computing and effective use of cutting edge multimedia technology in teaching.

**Joseph Gubeladze** works on K-theory of toric varieties and related commutative algebra and discrete geometry topics.

**Shandy Hauk** conducts mathematical, statistical, and naturalistic educational research to support people who teach and learn mathematics at all grade levels (including college) as well as inform the design and use of educational policy.

**Eric Hayashi*** (emeritus) has research interests in complex analysis, operator theory and frame analysis.

**Tao He’s** research interests include large scale genome-wide association studies, statistical inference on high-dimensional data and statistical learning.

**Serkan Hosten** works in computational and combinatorial commutative algebra, algebraic geometry and discrete geometry with applications in discrete optimization and algebraic statistics.

**Eric Hsu** is currently involved with several math education projects, including an NSF Math Science Partnership. He is interested in how teachers use the internet and live communities to learn to teach. He is also interested in how undergraduates learn calculus and use informal representations.

**Chun-Kit Lai's** research is in harmonic analysis and fractal geometry.

**Jean-Pierre Langlois's** research is in game-theoretic modeling of deterrence, bargaining and treaty design. He is the designer of the Gameplan game theory software.

**Ornella Mattei** works on the mathematical aspects of materials science. Specifically, her research focuses on the theory of composites, materials with time-dependent behavior and inverse problems.

**Sergei Ovchinnikov* (emeritus)** has current research interests in discrete mathematics and its applications in cognitive sciences.

**Alexandra Piryatinska** is interested in time series analysis and random fields and their applications to medicine and oceanography; Levy processes, parametric estimation problems and models of anomalous diffusion.

**Diane Resek*** (emerita) works on the development and popularisation of innovative curricula for teaching remedial mathematics.

**Neville Robbins*** has current research interests in number theory, particularly in linear recurrences and the theory of partitions.

**Dusy Ross** studies moduli spaces of curves, maps and sheaves, with an emphasis on investigating the mathematical realizations of physical dualities suggested by string theory.

**Alex Schuster's** research interests include spaces of analytic functions of one complex variable, especially the Hardy, Bergman and Bargmann-Fock spaces.

**Kim Seashore's** researches teachers' use of student thinking and formative assessment in order to achieve more equitable learning outcomes in mathematics.

**James T. Smith*** (emeritus) Completed The Legacy of Mario Pieri in Geometry and Arithmetic with Elena Anne Marchisotto (2007). A long-standing background project is investigation and implementation of computer techniques for doing and presenting mathematics.
