Biography

I am a third-year PhD student at the Computer Science department of University College London. I am fortunate to be advised by Prof. Ran Ben Basat and Prof. Brad Karp. My research interests are algorithmic design for networked systems, programmable networks, and distributed machine learning systems.

Before joining UCL, I received my B.S. degree (summa cumme laude) in Intelligence Science and Technology from Peking University.

You can download my latest CV here.
