I am a Postdoc Associate at the Computer Science and Artificial Intelligence Laboratory of MIT since November 2016, working with Prof. Samuel Madden and Prof. Michael Stonebraker. Before that I worked for IBM T.J. Watson Research Center as a Research Staff Member. I received my Ph.D. degree in Computer Science from Worcester Polytechnic Institute, supervised by Prof. Elke Rundensteiner. I have conducted research in the broad areas of data sicence and systems ranging from the low-level core database performance optimization to designing the high level, application specific machinelearning techniques. My recent research falls in the emerging area of "Systems for AI and AI for Systems", focused on designing scalable algorithms and systems for the data scientists to effectively yet efficiently explore and discover knowledge from heterogeneous data sources -- especially anomalies.
