I am Songbo Wang (汪嵩博), currently a PhD candidate in CMAP at the École polytechnique, which recently became part of the Institut polytechnique de Paris.
I work in probability theory, and more specifically, stochastic analysis, with applications in machine learning and physics.
A complete CV is available in PDF (English, français, 简体中文).
