Research

I work in computer vision, the area of computer science concerned with automatically interpreting semantic meaning from images, simulating the way a human views a scene.

At Cornell, I have been working with Professor Dan Huttenlocher on part-based object recognition algorithms.

Before coming to Cornell, I spent two years in the research labs of Eastman Kodak Company. There I worked mostly on smart image enhancement and understanding algorithms for consumer and medical images. You can try some of this technology by using Kodak PerfectTouch processing the next time you develop film or print digital photos on-line.

As an undergraduate and Masters student at Penn State University, I worked with Professor Rangachar Kasturi on content-based video indexing. We worked mostly on detecting, tracking and recognizing text in video (both captions and text appearing naturally in a scene).

Other projects

 These are other projects I've worked on that were never polished enough to be publishable, but that someone somewhere might still find interesting. :-)

Fun interests

 During the summer, my main obsession is cycling. I ride for fun only, and I have no delusions that I'm actually any good. My capstone ride for this summer was a 250-mile ride from Ithaca to Lake Erie along scenic Bike Route 17. I like to ski during the winter (aka the majority of the year in upstate New York), although I'm even worse at that.

I'm on a perpetual quest to become fluent in Spanish. In addition to taking classes in high school and throughout college and graduate school, I've studied abroad in Spain and Mexico, and I've also traveled to Puerto Rico and El Salvador. Despite all that effort, my Spanish is still remarkably lousy. :)
