**Robert McCann** (BScH '89 Queen's; PhD '94 Princeton) has played a leading role in the development of the theory and applications of optimal transportation. His 1994 thesis with Elliott Lieb introduced the concept of displacement convexity. Motivated by physical applications to interacting gases and equilibrium crystals, with collaborators he later extended such inequalities to curved settings, where they were shown to have a fundamental geometric significance, characterizing Ricci curvature bounds. He continues to explore the theory of optimal maps, and applications ranging from computer vision and weather prediction to nonlinear dynamics and economics. After holding an NSERC postdoctoral fellowship and Tamarkin Assistant Professorship at Brown University, in 1998 he accepted a position with tenure at the University of Toronto, where he remains. He has been lucky enough to hold visiting positions at IHES, MSRI, UC Berkeley, U Chicago, Courant Institute, MPI Leipzig, various universities in France and in Paris, among other institutions. He served as lead organizer for semesters of emphasis on Optimal Transportation at MSRI (2013), and on Variational Problems in Physics, Geometry and Economics at the Fields Institute (2014). He is a Fellow of the Royal Society of Canada, the American Mathematical Society, and the Fields Institute, and serves on the Editorial Boards of Advances in the Calculus of Variations, the Journal of Differential Equations, SIAM Journal of Mathematical Analysis, and as Editor-in-Chief of the Canadian Journal of Mathematics (since 2007). Currently holding a Simons Fellowship (2016), he was an invited speaker at the International Congress of Mathematicians in Seoul (2014).

**George C Papanicolaou** is currently the Robert Grimmett Professor in Mathematics at Stanford University. Besides his former focus on the analysis of waves and diffusion in inhomogeneous or random media, his recent research interests also include financial mathematics, especially the use of asymptotics for stochastic equations in analyzing complex models of financial markets and in data analysis. In 1987, the University of Athens conferred an Honorary Doctor of Science on Papanicolaou. In 2000, he became a Fellow of the American Academy of Arts and Sciences and he was elected to the U.S. National Academy of Sciences. Papanicolaou was invited plenary speaker at multiple international congresses, among others at the SIAM 50th anniversary meeting in 2002 and at the International Congress of Industrial and Applied Mathematics in 2003. In 2006, he received the SIAM von Neumann Prize in recognition of his wide-ranging work on analytic and stochastic methods and their application to the modeling of phenomena in the physical, geophysical, and financial sciences. In 2010 he received the William Benter Prize in Applied Mathematics. In 2011 he was the Gibbs lecturer of the American Mathematical Society. The University of Paris Diderot conferred on him the degree Doctor Honoris Causa in 2011.

**Gigliola Staffilani** has been the MIT Abby Rockefeller Mauze Professor of Mathematics since 2007. She received the B.S. equivalent from the University of Bologna in 1989, and the S.M. and Ph.D. degrees from the University of Chicago in 1991 and 1995. Following a Szego Assistant Professorship at Stanford, she had faculty appointments at Stanford, Princeton and Brown, before joining the MIT mathematics faculty in 2002 as tenured associate professor (professor in 2006). At Stanford, Professor Staffilani received the Harold M. Bacon Memorial Teaching Award in 1997, and was given the Frederick E. Terman Award for young faculty in 1998. She was a member of the Institute for Advanced Study in 1995-96 and again in 2003-04. She was a Sloan Fellow from 2000-02 and a Fellow at the Radcliffe Institute for Advanced Study at Harvard in 2009-10. In 2013 she became an AMS Fellow and a member of the Massachusetts Academy of Sciences. In 2014 she was inducted into the American Academy of Arts and Sciences. She received a Guggenheim Fellowship in 2017 and she will be a Simon Fellow in 2017-18.

Professor Staffilani is an analyst, with a concentration on dispersive nonlinear PDE. With her work she has contributed to the enormous progress that has been made in the last two decades in settling fundamental questions on existence of solutions for dispersive equations, as well as their long time behavior, singularity formation and interactions. This body of work has focused primarily on deterministic aspects of wave phenomena and it has been studied with sophisticated tools from harmonic analysis, nonlinear Fourier analysis, analytic number theory and geometry. More recently, though, a growing interest has been shown by the mathematical community in incorporating a nondeterministic point of view in the field of dispersive PDE and Staffilani's recent work has focused in advancing the field in this direction. Finally Staffilani is also interested on the study of the "process" used by mathematical physicists to pass from a complex system of particles interacting among each other to a macroscopic wave function that is able to describe the most important features of the system as a whole. More precisely, she studies the effective evolution equations arising as an appropriate limit of many body quantum dynamics.

**Tao Tang** graduated with a B. SC. in Mathematics from Peking University in 1984, and obtained a Ph.D. in Applied Mathematics from the University of Leeds in 1989. He was elected as an academician of the Chinese Academy of Science in 2017. He is currently the Vice-President, Dean of the Graduate School, and Chair Professor of Mathematics at Southern University of Science and Technology (SUSTech).

Professor Tang's main research interest is computational mathematics. He has made important and original contributions to the field of scientific computing, including the development of adaptive grid methods and the spectral method, and the establishment of the convergence theory for numerical methods for hyperbolic conservation laws. Professor Tang was awarded the Leslie Fox Prize for numerical analysis in 1988 and the Feng Kang Prize for scientific computing in 2003. He has also won the second prize of the National Natural Science Award in 2016.

He taught as a faculty member at Simon Fraser University from 1990 to 1998. In 1998 he joined the Hong Kong Baptist University and served as Chair of the Department of Mathematics, Dean of the Graduate School and Associate Vice-President.
