Research interests

I used to be a grad student in human-computer interaction. My research focused on visual ways to interact with data and models. I sometimes call this direct manipulation 2.0. For example, OmniGraphSketcher lets users visually manipulate quantitative data and ideas. And TeraFractal features an interface for directly and intuitively adjusting fractal parameters.

I am also interested in using this approach to take digital textbooks and reference works to their logical conclusion: interactive applications for learning, exploring, and referencing each area of study. GraphSketcher starts to do this for economics. TeraFractal starts to do this for fractal math. They are the tip of the iceberg.
