About Me

Hi, I’m a Ph.D. student supervised by Jimmy Lin in the David R. Cheriton School of Computer Science at the University of Waterloo starting from 2020. My research interests are dense retrieval for text search, including how to integrate lexical and semantic features into dense representations, its application to broader scenario, such as conversationa, multilingual and multimodal search.

Previously, I was a senior engineer at TSMC and working on improving CMOS image sensors through data analysis and knowledge of semiconductor. This experience shapes my research philosophy: human prior knowledge is the key to telling the story behind data and solving problems.
