One of challenges is to understand, access, and manage information with structures. This challenge is partially related to the limited cognitive resources of human beings, in terms of memory and attention, and partially due to the lack of information structures to guide information retrieval and sense-making. To help people deal with this issue, I am interested in using advanced visualization tools to improve the understanding of information, associated structures, and visually-guided user navigation in large information space. In this talk, I will discuss my current research projects on multiscale visualization of complicated (e.g., multi-dimensional data, social network data, and geo-spatial information) and sensemaking of research literature. I will also discuss a project on using process visualization to support common ground building in collaborative decision-making.
