My main research interest is improving the way we explore, analyze, and interact with complex data. To achieve this goal, I work on developing new techniques and methodologies in machine learning and computer vision.

My current research projects focus on algorithmic aspects of machine learning, particularly in the context of distributed learning, semi-supervised learning, active learning, multi-task learning, and transfer learning. I also investigate novel approaches for capturing, processing, mining, and visualizing image and video data.
