I am an Applied Research Lead at Meta AI. Prior to that, I was a principal scientist at Amazon AWS. I am also affiliated with The Open University of Israel, Department of Mathematics and Computer Science. My work is mainly related to computer vision, machine learning, statistical pattern recognition, and computer graphics. Much of my work relates to face images and videos, including face recognition, attribute prediction, face alignment, and 3D reconstruction of face shapes. I also worked on problems related to human action recognition in videos, dense correspondence estimation, feature representation and matching, and text image processing (OCR).
