His thesis focused on sampling class-independent object segmentation proposals using the CPMC algorithm, and on applying them in object recognition and localization. Systems authored by him and colleagues were winners of all four PASCAL VOC Segmentation challenges, 2009-2012. He did post-doctoral work at the Institute of Systems and Robotics in Coimbra, Portugal and is currently with the EECS department, at the University of California in Berkeley, USA. His research interests lie at the intersection of recognition, segmentation, pose estimation and shape reconstruction of objects from a single image.
