Yanbo Chen 「陈彦伯」

I am a third-year Ph.D. student in Computer Science at the University of Ottawa, advised by Andrej Bogdanov. My research interests are mainly in cryptography.

Before I came to Ottawa, I spent one semester at the Chinese University of Hong Kong. I received my B.Sc. in Computer Science in 2021 from Fudan University, where I also worked for one year as a research assistant, host by Yunlei Zhao.
