Rebecca Goldin

Associate Professor of Mathematical Sciences

Expertise: Symplectic geometry, group actions and related combinatorics

Rebecca Goldin is an associate professor in the Department of Mathematical Sciences in the College of Science and director of research for the Statistical Assessment Services, a nonprofit organization affiliated with George Mason University.

Her research investigates symplectic geometry, Hamiltonian group actions, equivariant cohomology, Schubert calculus, orbifold cohomology, classification of manifolds with group actions and statistics in the media.

She recently spoke at the Topology Festival at Cornell, at the "Moment Maps" conference in Spain and delivered the Falconer Lecture at the Mathematical Association of America MathFest. Gold received a B.A. from Harvard University and a Ph.D from the Massachusetts Institute of Technology.

Roman Polyak

Professor of Mathematical Sciences

Expertise: Linear and nonlinear programming, game theory, mathematical economics

Roman Polyak is a professor and holds a joint appointment in the Mathematical Sciences and Systems Engineering and Operations Research departments.

He developed a theory and methods for solving constrained optimization problems called nonlinear rescaling (NR) that has becomes essential in solving complicated, real-world technological problems with thousands of variables. NR has been applied to image processing, designing building structures, finding optimal distribution of electricity across a power grid and medical diagnostics including improving radiation therapy for cancer treatment.

Polyak received a Fulbright Scholarship Award in 2001 for his work on NR theory and applications of the NR methods. In 2003, he became and International Foundation for Research in Experimental Economics Fellow for his work in mathematical economics.

Padmanabhan Seshaiyer

Associate Professor of Mathematical Sciences

Expertise: Mathematics education, mathematical modeling and simulation, computational biomechanics

Padmanabhan Seshaiyer is an associate professor in the Department of Mathematical Sciences in the College of Science.

His research interests focus on mathematics education including enhancing learning with new technologies, mathematical modeling for teachers, multicultural education and K – 12 outreach. Seshaiyer can also discuss computational mathematics including numerical analysis computational biomechanics including fluid-structure interaction of blood flow through the arteries.

Seshaiyer has received several honors and awards including the President's Excellence in Teaching Award and currently serves on the Advisory Council for the Center for Teaching Excellence at Mason. He received a M.Sc. in Mathematics from Birla Institute of Technology and Science in Pilani, India, and a Ph.D. in Applied Mathematics from the University of Maryland, Baltimore County.
