Bojun Zhao

I'm a postdoc fellow at CIRGET based at UQAM, mentored by Steven Boyer and Duncan McCoy.

I completed my PhD at University at Buffalo in 2024. My thesis advisor is Xingru Zhang. Here is my CV.

I'm interested in the topics related to left orderable 3-manifold groups, taut foliations and pseudo-Anosov flows of 3-manifolds.
