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.
I am currently a postdoctoral researcher in machine learning/data mining at IBM T. J. Watson Research Center. I am interested in graph data analytics and their applications to data science and cyber security.

Research Interests
  • Data Science: graph spectral decomposition, graph mining, community detection, clustering 
  • Cyber Security: attack and defense models, action recommendations for network resilience, malware propagation models
