Qingcheng Zeng

I am a final-year PhD candidate focusing on LLMs and computational linguistics at Northwestern University, fortunate to be advised by Rob Voigt and Kaize Ding.

My research focuses on Agent Evaluation, Agentic RL, and Information Retrieval. Recent topics include:

• Agent Evaluation: Cross-Lingual Research, Knowledge Benchmarking
• Agentic RL: Co-work Agents, Confidence Calibration, Step Optimization
• Information Retrieval: Code-Switching Retrieval, Instruction Following

I also work on biomedical NLP, LLMs and cognitive science, and multilingual NLP.

Prior to Northwestern, I received my bachelor’s degree from Zhejiang University and the University of Manchester, with a focus on linguistics and formal logic. During my undergraduate studies, I worked extensively on speech processing.
