I am currently a postdoctoral researcher of AI Foundations at IBM Thomas J. Watson Research Center. My research interest includes graph data analytics and their applications to data mining, machine learning, artifitial intellegence, and cyber security.
I received my Ph.D. degree in electrical engineering and computer science (EECS) and M.A. degree in Statistics from the University of Michigan Ann Arbor in 2016, under the supervision of Prof. Alfred Hero.
