Jacob Bedrossian

University of Maryland, USA

Jacob Bedrossian is a Professor of Mathematics at the University of Maryland, College Park USA. His research interests are mainly the mathematical analysis of partial differential equations arising in incompressible fluid mechanics and plasma physics. Bedrossian and his collaborators have contributed to advances in hydrodynamic stability at high Reynolds number, random dynamics in stochastic models of fluids, and the kinetic theory of plasmas. In stochastic fluid mechanics, they proved the Batchelor spectrum of passive scalar turbulence, showed almost-sure, exponential mixing by the Navier-Stokes equations, and proved chaos for the Lorenz 96 model and for finite-dimensional approximations to the Navier-Stokes equations. In hydrodynamic stability, their contributions include the nonlinear inviscid damping of Couette flow, the determination of the subcritical transition threshold for 3D Couette flow, and the local well-posedness for vortex filaments in the 3D Navier-Stokes equations. In the kinetic theory of plasmas, a number of advancements were made regarding how weak collisions, nonlinear plasma echoes, and dispersive effects all affect Landau damping near homogeneous plasma equilibria. He was awarded a 2015 Sloan Fellowship, a 2016 NSF CAREER grant, the 2019 SIAG/APDE prize (joint with Nader Masmoudi), the 2019 IMA prize, and the 2020 Peter Lax award.
