I am a Professor in the Department of Computing and Mathematical Sciences at Caltech, where I currently serve as the Executive Officer, a.k.a., chair. I also serve as the Director of the Information, Science, and Technology (IST) initiative at Caltech. I am the founding Director of the Rigorous System Research Group (RSRG, pronounced "resurge") and an active member of the newDecision, Optimization, and Learning at the California Institute of Technology (DOLCIT) group. I participate actively in four centers at Caltech: I am currently co-director of the Social and Information Sciences Laboratory (SISL, pronounced "sizzle"), which focuses on the intersection of Economics and Computer Science. I am on the board of directors of the Linde Institute of Economic and Management Sciences. I am a member of the Center for the Mathematics of Information (CMI), which focuses on the intersection of Applied Mathematics, Electrical Engineering, and Computer Science. Finally, I am a member of 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, where you can find thoughts about research issues, conferences, academic life, and teaching. I am actively recruiting students and postdocs. See see this page for information on joining RSRG and this page for information on joining DOLCIT. Note that we have just started a new, unique, interdisciplinary PhD program in "Computing and Mathematical Sciences" available this fall. You can also take a look at my blog post about it for more information.
