My research efforts are primarily focused on three main thrusts in information sciences: Big data science, sparsity-based and compressive signal processing, and controlled sensing. I seek to understand the fundamental limits for signal reconstruction, data processing and acquisition, as well as design provable scalable and robust learning algorithms and efficient control policies towards achieving the overarching goals of various inference tasks at hand. I study these questions in the context of numerous concrete applications ranging from machine learning and video analytics, to optical imaging, to brain and array signal processing.
