Fan Zhang

Bio

I am a PhD candidate in the department of Computer Science at Cornell University. Under the able advice of Prof. Ari Juels, my research interest is in blockchains, trusted hardware, system security and applied cryptography. I'm particularly interested in understanding and building hybrid systems that enjoy the best of both blockchains and trusted hardware. I am a member of the exciting Initiative for Cryptocurrencies & Contracts (IC3). Before joining Cornell, I earned my bachelor's degree in Electronic Engineering from Tsinghua University in 2014.
