Welcome to my personal home page, which I update sporadically.

                 

If you've come this far, you're most likely looking for one of the following:

Or perhaps you're interested in one of my recent presentations:

 
 
 
You can also watch a video of my talk at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) on Set Retrieval 2.0.

A Brief History

After graduating from MIT with degrees in computer science and math and then completing a PhD at Carnegie Mellon, I joined the founding team of Endeca, where I am now Chief Scientist. I am proud to be one of the architects of Guided Summarization, a technology we use to power information access for e-commerce, enterprise search, and business intelligence. I run Endeca Research, a small team driving innovation in areas ranging from information extraction to query optimization, identifying and solving problems to invent Endeca's most exciting product capabilities.

Like my daughter, I'm also a big karaoke fan, though I had nothing to do with this masterpiece produced by some of our interns.

Graph Layout

Before discovering the joys of information access, I worked on graph layout (aka graph drawing), which can generously be called information visualization.

You can find my demonstration applet for JIGGLE (Java Interactive Graph Layout Environment) here, my dissertation here, and the source code here.

The source code is available for both non-commercial and commercial use; I only ask that you acknowledge the use of the software and let me know that you are using it. Besides, you might actually get me to help you with it that way!

You might also be interested my earlier paper describing a practical approach to drawing undirected graphs.
