I work on the foundations of the next generation of data-intensive and machine-learning applications. As our cities, factories, houses, vehicles, and devices are becoming increasingly networked, it becomes a necessity to analyze and transform into actionable knowledge massive high-dimensional Internet-of-Things data collections. My work focuses on (i) developing scalable and accurate methods to push the state of the art for supervised and unsupervised tasks; and (ii) building intelligent tools that harness such methods to solve real-world problems.
