Welcome to Cooperative AI Lab website! Our research aim is to enable machines to exhibit cooperative and safe behavior in intelligent decision making tasks. To this end, we work on multi-agent cooperation, human-AI coordination, and scalable alignment, which includes human value learning, safety, and ethics.

Welcome Edward Gunn and Jianing Zhao to join our lab as a PhD student
25 Jan 2026Three papers are accepted to ICLR 2026! Congrats to Zihao, Shuqing, Richard, and Hao! We're excited to share three RL-pure (100%) projects, focusing on multi-agent social dilemma evaluation, coalition learning, and RL exploration!
16 Oct 2025Four papers are accepted to EMNLP 2025! We explored Chain-of-Thought, training LLM via verifier-free RL, embodied manipulation, and spiral of silence in LLM agents
16 Oct 2025Five papers are accepted to NeurIPS 2025! We explored CoT Reasoning, Counterfactuals for Language Model Agents, Design Policy Learning, Generalizable and Scalable Policy Learning, and Evaluating Generalization Capabilities of LLM-Based Agents.
18 Mar 2025🚀 We’ve released SocialJax — a suite of sequential social dilemma environments for multi-agent RL in JAX, developed together with DeepMind researcher Joel Leibo. Built for speed, SocialJax leverages JAX’s GPU/TPU acceleration to scale MARL research. Code is available here
5 Dec 2024Welcome Dr Hao Liang to join our group as a postdoc! He will work on causality-inspired multi-agent RL.
1 Oct 2024Welcome Zihao Guo to join our group as a PhD!
27 Sep 2024Our project on Discipline hop for high-fidelity, high-generalisation models of human behaviour is funded by EPSRC, paternering with Matteo Leonetti (KCL) and Gustav Markkula from University of Leeds.
26 Sep 2024Five papers are accepted to NeurIPS 2025! We explored RL for cooperative games and LLMs for werewolves, football, human instruction following!
6 Sep 2024Exciting news! Nature Machine Intelligence has featured our work on decentralized multi-agent reinforcement learning for large-scale networked control, on cracking the scaling challenge of MARL. Welcome to check it out here!
1 Sep 2024Exciting news! Our review on safe RL entitled A review of safe reinforcement learning: Methods, theory and applications has been accepted to IEEE TPAMI. Congrats to Shangding! Read the preprint here!
2 May 2024One paper is accepted to ICML 2024. We explore Zero-shot Cross-task Preference Alignment for Robotic Manipulation. Earlier version appears on NeurIPS 2023 workshop on Optimal Transport.
