I am a Postdoc Research Fellow at NExT Research Center National University of Singapore (NUS), working with Prof. Tat-Seng Chua. I earned my PhD from NUS in June 2024, also supervised by Prof. Chua. My research interests include Natural Language Processing (NLP), Information Retrieval (IR), Document Intelligence (DI), and the application of AI in finance.

PS: I am actively looking for highly motivated PhD/master/undergraduate students to collaborate on various interesting research topics, including retrieval-augmented generation, multi-modal LLM for document intelligence, financial LLM, and LLM-based agents, etc. If you have interest, please feel free to send your CV to zhfengbin@gmail.com.
