I am a PhD student in NUS IDS&SoC work with Bryan Hooi, See Kiong Ng and Luu Anh Tuan(NTU). Previously I visisted UCL WI group and AI centre. Before that I worked as a R&D engineer in natural language processing working with Prof. Zhang Richong (张日崇), affiliated with BDBC and Computer Science College in Beihang University. My current research interests lie in LLM applications on task-oriented dialogue system, reasoning and calibration capability of LLM, as well as the LLM-powered Agent.
