I have graduated from The Hong Kong University of Science and Technology with First-class honor in Computer Science (2018), and currently as a visiting scholar at University Of California, Berkeley - Blockchain X-Lab. I am working on several blockchain research supervised by Professor Pan Hui: smart contract exploits, contract-level consensus, and decentralized oracles. I interned in Augmedix (San Francisco, 2016) on fullstack integration, and J.P. Morgan Chase (Hong Kong, 2017) on computational linguistics. I was an exchange student at the École polytechnique fédérale de Lausanne (Switzerland, 2017) studying reinforcement learning and pattern recognition.
