Current Research Interests:

My research interests fall in the general field of information networks and its intersections with power systems and social networks, with focus on stochastic modeling, optimization, and privacy/security aspects. 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.
