My research focuses on designing tools that augment human abilities for more effective data analysis and communication. I am particularly interested in the problem of human-machine configuration. Extensive research has been done to improve the efficiency and scalability of data systems and algorithms, but users are often added as an afterthought. It is a challenge to reconcile the inherent tension between automated data processing and the creative, flexible, but limited human mind. To achieve a tight coupling between the human and the machine, my work takes a holistic approach and contributes novel techniques, models and frameworks that inform the design of interactive data systems.
1. Designing and Creating Visualizations without Programming
If there exists a unifying framework that describes the composition and generation of data visualizations and information graphics, what are the building blocks of the framework?
2. Visual Analytics of Temporal Event Sequences
How do we combine users' domain knowledge and data mining algorithms for interactive analyses of temporal event sequence data?
3. Interactive Systems for Data Enthusiasts
What implications does interactive analysis have on the design of user interface, system framework and workload distribution?
