Hello, I am Xuandi Ren (任轩笛).

I am a third-year Ph.D student in the theory group of UC Berkeley, where I’m very lucky to be advised by Venkatesan Guruswami. Before joining Berkeley, I earned a B.S. in Computer Science from Peking University.

I have a broad interest in theoretical computer science, especially in Parameterized Complexity and Hardness of Approximation.
