    I am a postdoctoral researcher in mathematical quantum physics at Cermics, the laboratory of mathematics of the École des ponts, in the team of Éric Cancès. You can email me on long.meng@enpc.fr.

    My main research interests are relativistic and non-relativistic mathematical quantum mechanics, functional analysis, harmonic analysis, Strichartz estimate, numerical analysis and spectral theory.
