About
I am a final-year Ph.D. student at Large-Scale Data & Systems Group (LSDS) of Imperial College London, advised by amazing Marios Kogias. I am broadly interested in computer systems and programming languages. My research explores determinism as a foundational primitive for building reliable and robust systems that are easier to debug, reproduce, and reason about. I apply this perspective across multiple domains, including datacenter microservices, blockchain smart contracts, distributed databases, systems verification, and robotics.
Prior to joining Imperial, I was fortunate to work with Yiting Xia (MPI-INF) on hardware-accelerated datacenter networks, Marc Shapiro (INRIA) on actor-based distributed query processing, and Romain Jacob (ETHz) on P4-based failure-rerouting. I obtained M.S. from 脡cole Polytechnique and B.S. from South China University of Technology.
