๐ฌ Research Experience
AgentProcessBench | 2026.02-2026.03 RUCBM
Worked on process-level evaluation for tool-using agents. This project studies whether each step in a long-horizon, multi-turn tool-use trajectory is effective, using step-level annotations and unified evaluation protocols to analyze error localization, effective exploration, and error propagation in agent workflows.
AgentCPM-GUI | 2024.10-2025.02 OpenBMB
Worked on mobile GUI agents that execute natural-language instructions in real mobile applications. The project combines GUI grounding pre-training, supervised fine-tuning, and reinforcement fine-tuning to improve interface perception, planning, and action execution, with a focus on complex interactions in the Chinese mobile application ecosystem.
ProactiveAgent | 2023.10 - 2024.06 THUNLP
Worked on proactive LLM agents that move from passively responding to user requests toward actively offering assistance based on contextual needs. The project builds proactive task-prediction data from real user activities and uses human preference annotations and reward modeling to evaluate the appropriateness of proactive assistance.
