Daniel Jarrett

I am a Research Scientist at Google DeepMind working in the Gemini pre-training team.

I obtained my Ph.D. in Mathematics at the University of Cambridge, advised by Mihaela van der Schaar in the Machine Learning and Artificial Intelligence group. During such, I interned at Google DeepMind in the Deep Reinforcement Learning team, studying representation and exploration, and worked in the Game Theory team on language model training and alignment.

Research interests include generative modeling, reinforcement learning, and causal inference, focused on modeling, understanding, and improving decision-making over time. Previous life: investment banking, economic research, and software engineering. I hold an M.S. Computer Science from University of Oxford and B.A. Economics (Finance) from Princeton University.

Most of my work is only available within Google, but see publications for what is public.
