His academic credentials include: Ph.D. from the Courant Institute (1991) Habilitation from the University of Paris VII (Jussieu) (1996) Kamvissis specializes in infinite dimensional Hamiltonian systems that admit a Lax pair or zero curvature condition, which can be studied via inverse scattering/spectral methods. His research focuses on mathematically rigorous treatments of asymptotic problems for nonlinear dispersive systems, including long time behavior, semiclassical limits, and continuum limits of solutions to partial differential equations and nonlinear lattices. He has developed what he describes as a "nonlinear/non-commutative microlocal analysis" that extends classical stationary phase and steepest descent methods. His publication record shows a clear evolution from foundational work on the Toda lattice (1993-1996) through nonlinear Schrödinger equation studies (2003-2016) to his current focus on semiclassical WKB problems for non-self-adjoint Dirac operators (2020-2024). His approach integrates techniques from PDE theory, complex analysis, harmonic analysis, potential theory, and algebraic geometry, with particular attention to sophisticated models displaying instabilities. Professor Kamvissis maintains an active teaching schedule with courses planned through Spring 2026, including RIEMANN-HILBERT METHOD (Spring 2024), VON NEUMANN ALGEBRAS (Fall 2024), DIFFERENTIAL GEOMETRY (Spring 2025), RIEMANNIAN GEOMETRY (Fall 2025), and STOCHASTIC CALCULUS (Spring 2026).
