I am a research staff member at the IBM T.J. Watson Research Center, Yorktown Heights, NY. I am working on cognitive education projects specializing in personalized learning and visualization. I had worked as a Watson data scientist at Watson Life Group for Chef Watson. I received my Ph.D. in information science from University of Pittsburgh and worked as a postdoctoral NSF-CRA Computing Innovation Fellow at the Human-Computer Interaction Lab (HCIL), University of Maryland at College Park. My research interests are: user modeling, personalization, information retrieval, recommender systems, and visual analytics for intelligent systems.
I have participated in several projects on user behavior visualization and recommendation, open user profile for news recommendation, adaptive visualization for recommender/information retrieval systems, adaptive visualization for educational resources, knowledge structure visualization, and temporal network visualization.
