I am Weijia Zhang, a final-year Ph.D. candidate at Information Retrieval Lab, University of Amsterdam. I am honored to be supervised by Prof. Evangelos Kanoulas. I obtained my M.Eng. and B.Eng. degrees from the School of Electronics and Infomation Technology at Sun Yat-sen University, Guangzhou, China. My curriculum vitae is available here.

Research Interests

My primary research focuses on natural language generation (NLG) and large language models (LLMs). I specialize in retrieval-augmented generation (RAG), hallucination evaluation, and query-focused summarization (QFS).

I am actively seeking industrial positions for 2025, with a preference for opportunities in San Francisco Bay Area and Seattle. Please feel free to reach out if you believe I could be a good fit!.
