Dai (Ethan) Shi

Postdoctoral Research Fellow · University of Cambridge

I work with José Miguel Hernández-Lobato at the University of Cambridge on theory-grounded machine learning: generative models, reinforcement learning, stochastic analysis, operator learning, graph neural networks, multimodal LLMs, multimodal pretraining and mechanistic interpretability.

Before Cambridge I was at the University of Sydney as a research fellow with Professor Junbin Gao, 2023–2025. I was also a member of China's reserve team for the International Mathematical Olympiad (IMO).

Open to industry research roles. I am looking for research scientist roles in machine learning and scientific ML, and quantitative researcher roles. Email is the quickest way to reach me.

Do AI models see the same world?

A short video on our new paper, From Plato to Aristotle: Toward a General Theory of Representation Hypotheses. Studies disagree on whether different AI models converge to the same representations; we show that their alignment criteria sit at different points of one lattice.
