About
I am a PhD student at the School of Computing, Newcastle University, advised by Dr. Rich Davison and Dr. Gary Ushaw.
Prior to this, I studied in the MSc Computer Game Engineering programme at Newcastle University, graduating with Distinction. I also worked as a Game Engine Developer at Tencent Games and as a Game Developer at Shengqu Games.
My current research focuses on Large Multimodal Models and Reinforcement Learning.

Dawei Wang, Di Zhao, Xinyuan Liu, Marci Chi Ma, Xiaoyang Liu, Chengming Zhou, Gary Ushaw, Richard Davison
Proceedings of the 64th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers)
MARS-RA improves credit assignment in cooperative MARL by using large multimodal models to rank agents through pairwise contribution comparisons, converting these rankings into robust reward-shaping signals for effective cooperation.
Tracing the Light of Thought: A Probabilistic Self- and Cross-Consistency Verification Mechanism Improving Mathematical Reasoning in LLMs
Xiaoyang Liu, Dawei Wang, Tian Li, Huizhi Liang, Gary Ushaw, Richard Davison
Findings of the Association for Computational Linguistics: ACL 2026
We explored bridging ray tracing and LLM reasoning by proposing inference algorithms that sample reasoning trajectories directly based on LLM confidence at multiple granularities.
Towermind: A tower defence game learning environment and benchmark for llm as agents
Dawei Wang, Chengming Zhou, Di Zhao, Xinyuan Liu, Marci Chi Ma, Gary Ushaw, Richard Davison
Proceedings of the AAAI Conference on Artificial Intelligence
We introduce TowerMind, a tower defense game benchmark for evaluating long-term planning and decision-making in agentic LLMs, characterized by low evaluation costs, multimodal inputs, and reinforcement learning compatibility.
