Robert Strain

Robert Strain is a Professor of Mathematics at the University of Pennsylvania's Department of Mathematics. His research focuses on nonlinear partial differential equations, applied mathematics, and mathematical physics with particular emphasis on kinetic theory, free boundary fluid dynamics, and relativistic systems. He holds a prominent position in the analysis of complex fluid dynamics problems such as the Muskat problem, Peskin problem, and Vlasov-Maxwell systems.

His work bridges theoretical analysis and applied sciences, addressing fundamental questions in fluid mechanics, plasma physics, and nonlinear PDE theory. Strain has contributed to global existence and stability results for equations like the Boltzmann equation, Landau equation, and relativistic models. His research often involves rigorous mathematical techniques for boundary value problems and free interface dynamics.

Notable contributions include advancing understanding of Muskat bubble stability, relativistic plasma confinement, and nonlinear collisional kinetic theory. His publications span over 15 years, demonstrating sustained impact in both pure and applied mathematical analysis.
