Bio

I am a Ph.D. student in the department of Computer Science at Purdue University. I am very fortunate to be advised by Prof. Aniket Kate at FreedomLab. Previously, I obtained my Bachalor's and Master's degrees from Sun Yat-sen University, working with Prof. Wuhui Chen and Prof. Zibin Zheng.

My primary research interest lies in the field of blockchain technology. I am dedicated to developing scalable and secure blockchain protocols. Specifically, I am interested in many scalability solutions within blockchain, including sharding and Directed Acyclic Graph (DAG)-based State Machine Replication (SMR). I am also working on exploring order manipulation attacks in blockchain protocols and devising relevant prevention mechanisms.

In addition to doing research, I also enjoy singing. My friends call me Purdue's Eason Chan. My famous song - Half Moon Serenade, however, is created by another Cantonese singer Hacken Lee.
