I am currently a researcher of the Graph Computing Lab at Ant Research, working on cutting-edge techniques regarding high-performance graph storage and computation.

I was previously the CTO of FMA Technology, a big data company providing efficient and scalable graph processing solutions.

I received my PhD degree from the Department of Computer Science and Technology, Tsinghua University, advised by Prof. Wenguang Chen.
