Recent research in visualization has found that, as tasks get more complex, differences between users become more important. My work has shown how personality and cognitive ability affect the way people interpret visual structure.

Evaluation and Design

Nine black circles arranged in a square.  A red line connects all nine dots in an arrow-like pattern.Apart from my theory and experimental work, I try to bring a structural perspective to visualization design and evaluation. Here are some of the projects I've worked on in this area.

Structure in Visualization

 

Three red circles in a line, two of which are surrounded by a grey background fill.The focus of my research is on how visualizations structure information. How does the global organization of information in a visualization affect its meaning and its use? This research shows that minor aspects of design can strongly influence how people interpret visual information.
