Interests
My research interests are mainly in the problems of image & video recognition, detection and tracking, pose estimation, image & video generation, 3D reconstruction and super-resolution, with humans and their actions being the focal point of my research. I have approached these problems mainly using tools from Mathematical Optimization and Machine Learning. My current focus is on Compute & Data Efficient Deep Learning and its application to video recognition.Publications
