About Me

I am a fifth year graduate student in Computer Science at UMass - Amherst. I am a member of the Computer Vision Lab, advised by Al Hanson. Prior to UMass, I received a B.S. in Computer Science and Mathematics from Trinity College in Hartford, CT.

Research Interests

My interests primarily involve using cameras to (overtly) monitor people, with the goal being to provide information that is helpful to them in some way. For example, changes in an elderly person's health can be detected from fluctuations in their level of mobility. To this end, I am interested in tracking algorithms, activity recognition, and distributed sensor networks.

For more information, see the ASSIST Project website.

I have also implemented a large, public interactive display called The Molecular Playground
