Puxuan Yu, 余璞轩

Hi there! I am a 5th-year MS/Ph.D. student from the CIIR and CICS at UMass Amherst. I am advised by James Allan and Negin Rahimi. I obtained my bachelor's degree from Wuhan University in 2018.

My research interests lay in the intersection of information retrieval and natural language processing. More specifically, I work on applying NLP techniques into various IR tasks, such as entity retrieval and (multi-lingual) ad-hoc retrieval. My most recent works are about interpretable and explainable web search.
