Luis Caffarelli (wikipedia, homepage) from the University of Texas at Austin will receive the Shaw Prize 2018 in Mathematics (press release) for “his groundbreaking work on partial differential equations, including creating a theory of regularity for nonlinear equations such as the Monge–Ampère equation, and free-boundary problems such as the obstacle problem, work that has influenced a whole generation of researchers in the field.”
The Shaw Prize comes with a 1.2 million USD monetary award and is hence one of the world’s biggest prizes for mathematics.
Luis Caffarelli has already won several other major prizes in mathematics and is a member of several learned societies (link, link).
