Peter Constantin is the John von Neumann Professor of Mathematics and Applied and Computational Mathematics at Princeton University and the Director of the Program of Applied and Computational Mathematics. Constantin obtained his PhD in 1981 at The Hebrew University of Jerusalem under the direction of Shmuel Agmon with a dissertation on scattering for Schrodinger operators. Prior to coming to Princeton, Constantin was a Louis Block Distinguished Service Professor at The University of Chicago and the Chair of the Mathematics Department there. Constantin was a speaker at the International Congress of Mathematical Physics, Paris 1994, the International Congress of Mathematicians, Zurich 1994, and the International Congress of Industrial and Applied Mathematics, Edinburgh 1999. He is a ISI highly cited researcher, a Fellow of the London IOP, a SIAM Fellow, and Inaugural AMS Fellow, and a Fellow of the American Academy of Arts and Sciences.

Constantin works on Partial Differential Equations with emphasis on equations arising in nonlinear and statistical physics, and in particular on Euler, Navier-Stokes and related equations of fluid mechanics.

In relation to the Hidden Symmetries project, Constantin works on mathematical relevant questions of existence, regularity, uniqueness, qualitative properties, approximation and stability of solutions of MHD equations.
