Welcome to my homepage.
I am a PhD candidate in the Human-Centered Computing program at Georgia Tech , currently working in the Information Interfaces Lab. My advisor is Prof. John Stasko.
Research Interests
With the advances in data collection and storage technologies, it is now easier than ever for individual consumers, business corporations, research institutions and government agencies to generate massive amounts of data. It is widely acknowledged that there is a pressing need to transform these data from raw information into useful knowledge and actionable insights.
My research focuses on developing techniques and software tools to help people perform sense-making and exploratory data analysis, with an emphasis on interactive visualization interfaces. While visualizations have been generally recognized as effective in showing overall patterns, trends and outliers in data that cannot be captured otherwise, the real-world data we encounter are more complex. These data are often large in size, multi-dimensional, containing nominal attributes, or even unstructured. Understanding and analyzing these data constitute great challenges.
Taking a human-computer interaction perspective, my research integrates theories and techniques from the areas of databases, information visualization, data mining and cognitive science. My work can be organized under three themes:
- designing and implementing visual analytics systems for real-world sense-making problems (Jigsaw, SellTrend, NetClinic);
- theorizing the nature of user tasks and interaction in exploratory analysis from a cognitive perspective (Distributed Cognition and Model-based Reasoning);
- designing and implementing novel interaction mechanisms to support model construction and data transformation (Ploceus).
