Biography

I am a second-year DPhil student in the Department of Computer Science at the University of Oxford supervised by Professor Andrew Martin. I previously earned a Master’s degree from the University of Manchester and worked as a software engineer for six years.

My research explores the intersection of blockchain and AI with a focus on supporting model execution on chain in a secure and efficient way. The goal is to decentralise AI, increase openness and transparency, and enable secure autonomous collaboration among future AI systems. I use traditional verifiable computing technologies such as TEEs and ZKPs together with recent model specific methods to design proofs across the AI lifecycle including inference results, model compression and training data.
