Welcome to Shengwen's website!
My name is Shengwen Wang (王盛文). I am a lecturer at Queen Mary University of London. Previously, I completed my PhD at Johns Hopkins University in 2018 supervised by Jacob Bernstein.

Research interest:
Geometric analysis and geometric PDEs. I am interested in understanding the formation of singularities and developing/improving regularity theory of geometric partial differential equations such as minimal surfaces, mean curvature flows, Allen-Cahn and Ginzburg-Landau equations, etc.
