Alexis Vasseur
Schlumberger Chair for Mathematical Sciences
Mathematician Alexis Vasseur studies the equations governing fluids to understand how complex phenomena such as shocks, turbulence, and singularities emerge and evolve.
Alexis Vasseur is the Sid W. Richardson Chair in Mathematics at the University of Texas at Austin. He specializes in the mathematical analysis of partial differential equations applied to fluid mechanics, working at the interface of Navier-Stokes equations, hyperbolic conservation laws, kinetic equations, and hydrodynamic limits.
A former student of the École Normale Supérieure (Paris), Alexis Vasseur completed his Ph.D. at Pierre et Marie Curie University (now Sorbonne University). Before Joining UT, he held a CNRS permanent research position at the University of Nice (France). He also held a professor position at the University of Oxford (UK).
Recently, Vasseur’s work focuses on the stability of shock waves and other discontinuous solutions to compressible fluids, using a-contraction and relative entropy methods, as well as on regularity questions for fluid and kinetic models.
