Bio

I am a Junior Research Fellow starting from October 2024 at Trinity College, University of Cambridge. Before that, I was a research associate at the Machine Intelligence Laboratory, University of Cambridge working with Prof. Phil Woodland. I am also closely collaborating with Prof. Chao Zhang at Tsinghua University. My research interest is controllable and reliable multimodal conversational AI with large language models. Specifically, this includes multi-modal contextual knowledge integration, reliability, hallucination reduction, and multimodal contextualised AI safety. My research interest and experience also include speaker diarisation, language modelling and speech synthesis.

I completed my Ph.D. in June 2023. My Ph.D. at the University of Cambridge supervised by Prof. Phil Woodland (advisor Prof. Mark Gales) on contextual knowledge integration in end-to-end neural-based conversational AI systems. I held a research internship at Google Brain with Dr Yu Zhang in 2019 and ByteDance with Dr Wei Li in 2023. I was also grateful to have collaborated with Poly AI Ltd working with Dr Ivan Vulić and Dr. Paweł Budzianowski in 2023. I received by B. A and M.Eng degree in 2019 at Trinity College, University of Cambridge.
