Meghan Fazzi joined the Simons Foundation in 2008 after working for seven years as an executive assistant at the American Institute of Mathematics in Palo Alto, Calif. She assists MPS director Yuri Tschinkel, and helps to develop and coordinate the Simons Science Series, Simons Symposia and Science Lives projects.


Emily Klein

Program Associate, Mathematics and Physical Sciences

Emily Klein joined the foundation in 2015 to support programs in Mathematics and Physical Sciences. Previously, she coordinated medical education programs and assisted with grants at the Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai in New York City. Prior to Tisch, she worked at the Juvenile Diabetes Research Foundation, where she focused on pre-award grants management.

Andrew Millis, Ph.D.

Associate Director for Physics

Andrew Millis is associate director for Physics at the Simons Foundation. Millis is also a professor in the physics department at Columbia University, where he has been on the faculty since 2001 and served as department chair from 2006-2009. He received his Ph.D. from the Massachusetts Institute of Technology in 1986. Prior to joining the Columbia faculty, he worked for ten years in the Theoretical Physics Research group at Bell Laboratories and served on the faculty at Johns Hopkins University and Rutgers University. Millis’ research interests are in the area of theoretical physics, with a particular focus on the properties of interacting electrons in solids and nanostructures.

His recent work has emphasized the development and use of new numerical methods for the many-electron problem and the application of these methods to elucidate the behavior of high temperature superconductors, oxide superlattices, and materials under non-equilibrium conditions. He is the author of more than 250 papers and has served on numerous advisory boards, including that of the Kavli Institute for Theoretical Physics. He is currently a trustee of the Aspen Center for Physics, a foreign associate of the Canadian Institute for Advanced Research and a fellow of the American Association for the Advancement of Science. Two of his recent postdoctoral fellows have received IUPAP Young Scientist awards.

Elizabeth Roy

Elizabeth Roy, M.S.

Senior Program Manager, Mathematics and the Physical Sciences

Elizabeth Roy joined the Simons Foundation in 2010. She worked previously at the Juvenile Diabetes Research Foundation (JDRF) as research administration manager focusing on pre-award grants management. Prior to JDRF, she worked as a systems project leader at Kraft Foods responsible for Web analytics and the Web sites for several Kraft brands. She earned an undergraduate degree in computer science from Pace University and a master’s degree in political science with a focus on international relations and comparative politics from Fordham University.

Yuri Tschinkel, Ph.D.

Yuri Tschinkel, Ph.D.

Director of Mathematics and the Physical Sciences

Yuri Tschinkel received his doctorate in mathematics from the Massachusetts Institute of Technology in 1992. From 1992–95 he was Junior Fellow of the Harvard Society of Fellows, and from 1995–96 he was a Leibniz fellow at the École Normale Supérieure in Paris.

Prior to joining the Simons Foundation in 2012, Tschinkel was a faculty member at the University of Illinois at Chicago, a visiting associate professor at Princeton University, the Gauss chair of mathematics at the University of Göttingen, and professor and chair of the mathematics department at the Courant Institute, New York University.

He was also a member of the Institute for Advanced Study in Princeton and held visiting fellowships at the Isaac Newton Institute for Mathematical Sciences in Cambridge, University of Tokyo, Max Planck Institute in Bonn, Institut des Hautes Études Scientifiques in Paris, Eidgenössische Technische Hochschule Zürich, and Research Institute for Mathematical Sciences at Kyoto University. He was an invited speaker at the International Congress of Mathematicians in Madrid in 2006.

He serves on the editorial boards of Algebraic Geometry, Experimental Mathematics, the Bulletin of the American Mathematical Society, the European Journal of Mathematics, and the Progress in Mathematics series from Birkhäuser. He is a member of the Scientific Council of the Fondation Sciences Mathématiques de Paris and has served on several other advisory boards.

Tschinkel’s research is at the interface of algebraic geometry and number theory. He studies higher-dimensional algebraic varieties, their hidden symmetries and rational points. He is the author of 100 papers and editor of 15 books. He is a Fellow of the American Mathematical Society and of the American Association for the Advancement of Science.
