My research focuses on computer vision and machine perception. I'm interested in understanding the world from visual information, including understanding events, scenes and activities, detecting and tracking people, as well as object detection and segmentation. I'm also interested in exploring how systems can use and improve their understanding by interacting with the world and by being user-focused, which has driven my work in robotics and human-robot interaction.
I'm currently a Research Scientist at Google, Inc.Previously I was a Research Scientist at Willow Garage, Inc., a personal robotics research lab.
I completed my doctoral work at The Robotics Institute, Carnegie Mellon University, advised by Martial Hebert. I also spent time at INRIA Rhône-Alpes working with Cordelia Schmid. My thesis explored the use of unsupervised image segmentation to improve object recognition.
