Puxuan Yu

Hi there. I am a second-year MS/Ph.D. student from the CIIR and CICS at UMass Amherst. My advisor is Prof. James Allan. I obtained my bachelor's degree from the School of Computer Science at Wuhan University in 2018.

Currently, I am interning with Dr. Hongliang Fei and Dr. Ping Li at Baidu Research USA.

My research interests lay in the intersection of information retrieval, machine learning and natural language processing. More specifically, I work on representations in various retrieval tasks, such as entity retrieval, (cross-lingual) ad-hoc retrieval, and product search & recommandation. My past research was about intent-aware privacy protection for personalized web search.
