I am currently a Lecturer-Researcher at the Department of Mathematics, FPT University, Da Nang. Previously, I was a Lecturer at the University of Da Nang and a Boya Postdoctoral Fellow at the Beijing International Center for Mathematical Research, Peking University. I earned my Ph.D. in Mathematics at the University of Wisconsin–Milwaukee (2019), under the supervision of Prof. Chris Hruska.. Here is a copy of my CV.
My research interests lie in geometric group theory and low-dimensional topology.
