I am an incoming Fall 2026 student at the University of Illinois Urbana-Champaign (UIUC) and a graduate of Shanghai University of Finance and Economics (SUFE) with a B.S. in Business Analytics.

My research and engineering interests center on Large Language Models (LLMs), Multimodal Models, Coding Agents, and FinTech. I enjoy bridging cutting-edge model research with real-world industrial systems.

My research experience includes work with the Tencent Youtu AI Lab on LLM safety and multimodal research, the SUFE FinAI Center (advised by Prof. Liwen Zhang, 张立文) on financial reasoning and agent safety, Shanghai Jiao Tong University (advised by Prof. Xiaodong Gu, 顾小东) on LLM for Code, and the Head Office of ICBC (Private Banking Department) on scientist-discovery agents.

Research Interests

• Large Language Models — SFT / GRPO / PPO, reasoning, distillation, alignment
• Multimodal Models — vision–language–video embeddings, retrieval, fusion
• Coding Agents & RAG — code generation, repair, tool use, planning
• AI for Finance — financial reasoning, agent safety, knowledge graphs
• Content Safety — multi-label moderation, low-resource & few-shot detection

Selected Highlights

• 📝 FinVault — Benchmarking Financial Agent Safety in Execution-Grounded Environments — arXiv preprint. arXiv:2601.07853
• 📝 RVCFT — Reasoning-Visual Critical Token Fine-Tuning for Multimodal Reasoning — manuscript.
• 📝 VeriBRT — Plan-Guided, Evidence-Based Automated Bug Reproduction — manuscript.
• 🛠️ ARH (AI Research Helper) — open-source CLI-first research assistant agent with tool use, three-layer memory, skill self-learning and multi-LLM fallback. github.com/LiRunGuo/Arhelper
