About Us: Faculty Research Interests

Keith Burns PhD, Warwick University (England)
Keith Burns works on geometrical and dynamical problems connected with geodesics in manifolds with nonpositive curvature. Recent work has concentrated on partial hyperbolicity and stable ergodicity.

Frank Calegari PhD, University of California at Berkeley
Calegari's work in number theory includes the study of Galois representations, in particular their connection to modular forms. He also studies the geometry and analysis of p-adic modular forms. Another interest is the application of arithmetic to questions in geometric topology.

Gui-Qiang Chen PhD, Academia Sinica
Chen's current research on nonlinear partial differential equations focuses on conservation laws, free boundary problems, nonlinear waves, and related problems.

Kevin Costello PhD, University of Cambridge
Costello's interests include algebraic structures related to the moduli spaces of Riemann surfaces, mathematical aspects of string theory, and non-commutative geometry.

Matthew Emerton PhD, Harvard University
Emerton works in number theory and arithmetic geometry. Much of his work has focused on the arithmetic theory of modular forms, using methods both of geometry and of representation theory. He also studies the theory of D-modules on varieties in finite and mixed characteristic.

Stephen Fisher PhD, University of Wisconsin

John Franks PhD, University of California, Berkeley
Franks's recent topological work has focused on actions of groups on surfaces -- in particular, lattice actions which leave invariant a Borel probability measure on the surface. Some of his earlier work concerned knots that occur as closed orbits of flows, index arguments using the zeta function, subshifts of finite type, attractors, and descriptions of possible dynamics.

David Nadler PhD, Princeton University

Mark Pinsky PhD, Massachusetts Institute of Technology Pinsky has worked in probability theory, specifically diffusion processes on manifolds. In recent years he has become interested in classical Fourier analysis, investigating the various implications of the "Pinsky phenomenon".

Stewart Priddy PhD, Massachusetts Institute of Technology
Priddy's research on the structure of stable homotopy theory uses group theoretic constructions and the tools of group cohomology and modular representation theory.

R. Clark Robinson PhD, University of California, Berkeley
Robinson's research in dynamical systems uses analytic and geometric methods. Recent work includes questions relating to attractors, correctly aligned windows to get invariant sets, applications of stable manifold theory to celestial mechanics, and Melnikov method applied to higher dimensional Hamiltonian systems to insure horseshoes.

Michael R. Stein PhD, Columbia University
Stein's current research focuses on certain extensions and generalizations of braid groups. He is also interested in questions concerning central extensions and Schur multipliers of Chevalley groups and Kac-Moody groups over commutative rings.

Andrei Suslin PhD, Leningrad State University
Suslin has made fundamental contribution to algebraic K-theory with special emphasis on higher algebraic K-theory and its connections with and applications to algebraic geometry and algebraic number theory. Suslin is a Board of Trustees Professor of Mathematics.

Dmitry Tamarkin PhD
