About me

I am a Professor in the Department of Computing and Mathematical Sciences at Caltech where I am a member of the Rigorous System Research Group (RSRG, pronounced "resurge").

I also participate actively in three centers: the Center for the Mathematics of Information (CMI), which focuses on the intersection of Applied Mathematics and Computer Science; the Social and Information Sciences Laboratory (SISL, pronounced "sizzle"), which focuses on the intersection of Economics and Computer Science and is part of the Linde Institute of Economic and Management Sciences; and the Resnick Sustainability Institute, which is an interdisciplinary initiative at Caltech connecting researchers focused on energy related issues from all across the campus. I also maintain an academic blog, titled Rigor + Relevance.

My research

My research focuses on three seemingly distinct areas: cloud computing, network economics, and power systems. Though diverse, the areas are all essential to my broader research goal: easing the incorporation of renewable energy into IT and, more generally, into the electricity grid. Broadly, my particular research style can be described as: "Rigorous system design." I use mathematical models to provide insight into the design of computer systems, markets, and power systems by applying techniques from algorithms, operations research, economics, and control. Some examples of topics that I'm focusing on these days are:
