Visual Metaphors

My thesis research is on the use of visual metaphors as a general framework for understanding how visual structure affects visualization use.  Infovis theory has mostly focused on the visual properties of objects, which has made it possible to apply work in perception to visualization design. My work similarly attempts to understand the conceptual structure of visualization, making it possible to apply knowledge from human cognition.  Visual metaphors are a useful foundation, since conceptual metaphors are well-studied and can be easily applied to a variety of structural issues.

Cognition in Visualization

I am also interested more generally in the cognitive aspects of visualization use.  For example, how do different presentations of maps lead to different conceptions of space?  What does cognitive science imply for interaction design?  And how can we reconcile the visualization community's ideas about insight with insight's definition in cognitive science?

Apart from my theory and experimental work, I try to bring a structural perspective to visualization design.  Here are some of the smaller design projects I've worked on.

Forked Parallel Sets
Mixed categorical and continous data to analyze dimensional relationships

Blob Networks
Categorical data as a network
