I am a fourth year PhD student at Purdue University, studying machine learning in relational domains with Professor Jennifer Neville. I have interests in relational learning, particularly in partially observed network domains. I also study generative graph models for understanding how large networks form, and using them for anomaly detection. In addition, I am interested how incentivization can affect network sharing behavior, and how companies can use this to reach out to a large user base. Previously, I worked on robotics, where I worked on localization of objects when grasping.
