About Me

I am currently a postdoc at Technion probability group hosted by Prof. Oren Louidor. I obtained my Ph.D. at probability group in Peking University under the supervision of Prof. Yan-Xia Ren in 2025.

Research

I’m interested in probabilistic models, particularly those that incorporate tree structures. I am trying to learn and work on more interesting subjects, e.g.,
