about me
I finished my Ph.D. at Cornell University, co-advised by
Prof. Emin Gün Sirer and
Prof. Robbert van Renesse.
I also worked closely with Dr. Dahlia Malkhi.
I focused more on fundamental problems
of fault-tolerance, consensus protocols and peer-to-peer systems. My taste of research is to build the systems which
are provably correct and practically effective. Currently, I am tackling challenges
in blockchains, from a system perspective. I am looking for research collaboration
and a faculty position.
