Bio

Chang Liu entered the SC&I Ph.D. program in Fall 2007. She received a BS in LIS and a BS in Economics from Peking University, and a MS in LIS from Peking University. Her research focused on interactive information retrieval area, and the method is by conducting user studies, to identify users’ behavioral evidence about their preference and contextual factors, and then incorporate such evidence in the design of retrieval systems. She is now working as a GA for Poodle Project, "Personalization of Digital Library Experience" funded by the Institute of Museum and Library Services (PI. Dr. Nicholas Belkin, Dr. Jacek Gwizdka, and Dr. Xiangmin Zhang). She participated in TREC Session Track 2011 and 2012 as a member of the Rutgers team. She recently successfully defended her dissertation "Personalizing Information Retrieval Using Interaction Behaviors in Search Sessions in Different Types of Tasks".
