I am research assistant professor at NYU-Poly. My current research theme is on the design of interactive information visualization techniques and in the algorithms to produce such visualizations. For example, in a recent paper we proposed the idea of using tag-cloud lenses coordinated in multiple views as a natural way to investigate bird habitat preferences predicted by a statistical model developed at the Cornell Lab of Ornitology. This technique can be applied in many other domains such as census maps and twitter topic maps.
The flow of patients interactions with the healthcare system is another project I have been working on.
In a more theoretical work, I have been studying a mathematical characterization that unifies the notion of graph edit distance metrics and subgraph-based metrics. This characterization makes it easy to see different distance metrics on complex objects. For instance it is easy to generalize previous metric formulas on simply labeled graphs to work on graphs whose node and edge labels are itself graphs.
I have also worked on a generalization of vector drawing systems (e.g., Inkscape, Illustrator) that handles data and that naturally supports mixing and matching visualization techniques (e.g. plotting, network drawing). Our hypothesis is that the free-form interactive composition flow of this system can be effective when exploring heterogeneus data. Our prototype system based on this generalization of vector drawing systems is called called Defog.
