About Me
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, 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.
