I work in computer vision, the area of computer science concerned with automatically inferring semantic meaning from images -- teaching computers to "see." More generally, I am interested in problems that involve analyzing and modeling large amounts of uncertain data, like mining data from social networking websites.
I'm an Associate Professor in the School of Informatics, Computing, and Engineering at Indiana University, where I direct the IU Computer Vision Lab. I'm on the faculty of the Computer Science, Informatics, Cognitive Science, and Data Science programs, and I'm adjunct in the Department of Statistics. My work has been funded by grants and contracts from the National Science Foundation (including through a CAREER award), Google, Kodak, the Department of Defense, and Indiana University.
Before joining IU, I was a graduate student and postdoc in Computer Science at Cornell University. I worked with Professor Dan Huttenlocher on statistical part-based object recognition algorithms, and with Professor Jon Kleinberg on modeling and mining data from online social networks. I completed the Ph.D. degree in August 2008.
Before Cornell, I spent two years in the research labs of Eastman Kodak Company. There I worked mostly on image understanding and enhancement algorithms for both consumer and medical images.
As an undergraduate and Masters student at Penn State University, I worked with Professor Rangachar Kasturi on content-based video indexing, and specifically on detecting, tracking and recognizing text in video (both captions and text appearing naturally in a scene).
My current preferred winter activity is swimming in IU's fantastic pools. (My unofficial hobby is to swim in a public lap pool in as many cities of the world as possible (so far: Amsterdam, Barcelona, Beijing, Blacksburg, Bloomington, Boulder, Chicago, Columbus, Copenhagen, Dallas, D.C., Denver, Detroit, Erie, Fort Collins, Glasgow, Hong Kong, Honolulu, Indianapolis, Ithaca, Jamestown, Jerusalem, Kailua-Kona, Las Vegas, Los Angeles, Madrid, Minneapolis, Montreal, Munich, Nashville, New Orleans, Newcastle upon Tyne, Paris, Phoenix, Quebec City, Salt Lake City, San Diego, San Jose, Santiago, Seoul, Shanghai, State College, Sydney, Tokyo, Vancouver, Venice).
I took piano for 12 years as a child and recently started picking it back up again. I've also been trying to learn organ. Since I can't produce great music myself, I'm happy to live just a few blocks from the amazing IU Jacobs School of Music.
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, Chile, and El Salvador. Despite all that effort, my Spanish is still remarkably lousy. :)
