Panagiotis E. Souganidis

Panagiotis E. Souganidis (Παναγιώτης E. Σουγανίδης) is a Greek-American mathematician, specializing in partial differential equations.

Souganidis graduated in 1981 with B.A. from the National and Kapodistrian University of Athens. At the University of Wisconsin–Madison he graduated with M.A. in 1981 and Ph.D. in 1983 with thesis under the supervision of Michael G. Crandall. Souganidis was a postdoc in 1984–1985 at the University of Minnesota's Institute for Mathematics and its Applications and was at the Institute for Advanced Study in 1988 and 1990. After holding professorships at Brown University, the University of Wisconsin–Madison, and the University of Texas at Austin, he became in 2008 the Charles H. Swift Distinguished Service Professor in Mathematics at the University of Chicago. He has held visiting positions at academic institutions in Italy, Japan, Greece, France, the UK, and Sweden.

He works on non-linear partial differential equations, and stochastic analysis. The main parts of his work are qualitative properties of viscosity and entropy solutions, front propagation and asymptotic behavior of reaction diffusion equations and particle systems, stochastic homogenization, the theory of pathwise solutions for first and second order partial differential equations, including stochastic Hamilton-Jacobi equations and scalar conservation laws.

Souganidis is the author or co-author of over 100 publications in refereed journals. His wife is Thaleia Zariphopoulou, a Greek-American mathematician and professor at the University of Texas at Austin.
