Xingyu Deng

I am a second-year PhD student at the University of Sheffield, working on scientific fact-checking under the supervision of Dr. Xi Wang and Dr. Mark Stevenson. Broadly, I am interested in topics related to fact-checking, including information retrieval, retrieval-augmented generation (RAG), and natural language processing for verifying scientific claims. My existing work focuses on bridging the gap in evidence retrieval for scientific fact-checking, developing specialised retrieval systems capable of handling complex, full-paper scientific literature rather than simplified abstract-level datasets.

Prior to beginning my PhD journey, I earned my bachelor’s and master’s degrees in Computer Science at the University of Manchester. I became interested in AI during a research project supervised by Prof. Steve Furber, and later explored healthcare fact-checking in my master’s project under the supervision of Prof. Goran Nenadic. I am especially grateful to my tutor Dr. Oliver Rhodes, whose support and encouragement helped me navigate a particularly challenging period.
