I am currently a Research Assistant at UC Berkeley, working with Postdoctoral Researcher Shangding Gu and Prof. Dawn Song. Previously, I was a Research Assistant at The Hong Kong University of Science and Technology (Guangzhou), advised by Prof. Jiaheng Wei. Before that, I was a Machine Learning Engineer at Ant Group from July 2024 to July 2025. I received my Master’s degree from King’s College London.

My research interests focus on developing and benchmarking Multi-Agent LLM/VLM Systems to enhance reasoning capabilities and enable complex real-world interactions:

• Evaluation & Benchmark: exploring multi-agent LLM/VLM systems for buyer-seller transaction negotiations [AgenticPay] (NeurIPS 2026 Main Track). 📍UC Berkeley

• Post-training & Reasoning: generating synthetic reasoning data via multi-agent frameworks to enhance mathematical reasoning [AgenticMath] (AAAI 2027 stage 2 under review). 📍HKUST(GZ)

• Multi-Agent Framework: developing knowledge graph-driven agent orchestration framework that combines LLM/VLM with Eventic Knowledge Graph (EKG) for complex reasoning and online collaboration [MuAgent ]. 📍Ant Group
