Scholar-generated biography
Alexandru Ionescu is a mathematician at Princeton University whose research focuses on partial differential equations, harmonic analysis, and mathematical physics. His work addresses global well-posedness of dispersive equations such as the Benjamin–Ono equation, gravity water waves, and Schrödinger maps. He investigates nonlinear fractional Schrödinger equations, Euler-Maxwell systems, and energy-critical NLS equations. Ionescu also studies inviscid damping near shear flows and spectral properties of Schrödinger operators with rough potentials. His research emphasizes low-regularity spaces, Sobolev spaces, and regularity theory for polyhedral domains. These studies contribute to understanding long-time behavior and stability of solutions in mathematical physics and fluid dynamics.
