Current Research Interest
My research interests fall in the general field of information networks and data science, including communication networks, Internet of Things (IoT), Fog Computing, social networks, smart grid. My current research focuses on fundamental problems in information networks and data science, including Fog Computing and its applications in IoT and 5G, IoT data privacy/security, optimization/control of mobile social networks, cognitive radio networks, stochastic modeling and control for smart grid. Together, these areas have a wide range of intellectual emphasis. My research draws on a synergy of advanced mathematical tools to deliver practical network solutions. I believe that to make great impact, engineering research should be application-driven and should bridge theory and practice, and researchers should build a broad spectrum to tackle the challenges in cutting-edge applications and meet the societal demands therein.
