Employment
Experience
- MedSnaphttp://www.medsnap.com
MedSnap is a mobile application to assist in the identification of pills. I developed the computer-vision algorithm prototype, the data-model for statistical models, and systems to collect and qualify reference data.
- Autonomous Canine Systemhttp://goo.gl/YijBzk
While working as a research assistant at Auburn, I helped to design and develop a system for the autonomous navigation of a trained canine. This system used GPS, magnetometers, and accelerometers to determine the dog's position. These inputs were fed into an expert system which determined the next command to issue to the dog.
