Biographical Overview

Laurent Demanet is Professor of Applied Mathematics in the Department of Mathematics at MIT, with a joint appointment in Earth, Atmospheric, and Planetary Sciences. Previously, he held a postdoctoral position called "Szego assistant professor" in the Department of Mathematics at Stanford. He obtained his Ph.D. in 2006 under Emmanuel Candes, in Applied and Computational Mathematics at Caltech. He completed his undergraduate studies in mathematical engineering and theoretical physics at Universite de Louvain, Belgium. He is the recipient of a Sloan research fellowship, a CAREER award from NSF, and a Young Investigator award from AFOSR. His research interests include seismic imaging, geophysical inversion, and machine learning.
