About me

I’m a PhD student in Computer Science at the Networks and Mobile Systems Group (NMS) of MIT CSAIL, advised by Prof. Mohammad Alizadeh. My research is focused on computer networks and distributed systems. I received my SM from MIT in 2020 and my BS in Computer Science from Peking University in 2018.

I love designing and building systems that are robust, performant, and easy to use. My current research focuses on computer network problems in the setting of blockchain. Two examples are Prism, a cryptocurrency that supports more than 80,000 transactions per second, and DispersedLedger, a method that allows BFT state machine replication protocols to run well on variable-bandwidth networks. My work is supported by Ethereum Foundation.

Occasionally, I write about what I do in my blog. When away from the keyboard, I enjoy hiking, cycling, sailing and travelling. Plus, I am a licensed amateur radio operator. My callsign is KC1NOR.
