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. I obtained my bachelor's degree from Wuhan University in 2018.

My current research interest is to improve the information organization of user interfaces and enhance the interpretability of text search systems. The goal is that search engine users could easily understand the decision-making process of IR systems in various aspects, such as relevance and diversity.
