Ben Pineau
I'm a recent PhD graduate from the mathematics department at UC Berkeley. My main area of study is in nonlinear partial differential equations. Here is my CV.
I am currently a Simons Junior Fellow in the Simons Society of Fellows and am hosted by the Courant Institute of Mathematical Sciences in New York City. My mentor is Vlad Vicol.
My research interests are generally in physically motivated models, some of which include Schrödinger equations, free boundary Euler equations, water waves, and the equations of magnetohydrodynamics. I am also interested in stable phase retrieval.
My advisor was Daniel Tataru. My dissertation can be viewed here.
