Research Statement
My research interests broadly lie in distributed systems, spanning cloud computing, distributed consensus, fault-tolerant computing, real-time analysis, and large-scale intelligence. I enjoy conducting fundamental research. I am driven to contribute to cutting-edge work that has a tangible, positive impact on our lives.
