Hi, I am Yiming (Elvin) DU. I am a PhD candidate at the Chinese University of Hong Kong, pursuing my PhD in the Department of SEEM at CUHK under the supervision of Professor Kam-Fai Wong. I conduct my research at the MoE Key Laboratory of High Confidence Software Technologies (MoE Lab), which is led by Professor Wong. I am currently a visiting scholar at EdinburghNLP, working with Jeff Z. Pan.

My current research focuses on Memory, Dialogue System and Data Selection. I am particularly interested in memory reasoning, reinforcement learning in Agent Memory and applications in personal assistant.
