Yulan Qing

I am a tenure-track Professor at Fudan University (SCMS). My research interests lie in low-dimensional topology and geometric group theory. My current research focuses on the geometric and dynamical aspects of finitely generated groups and their automorphism groups. In particular, the geometry of Out(Fn) and non-positively curved groups have been the center of my work.
