I am a social scientist and statistician. Much of my research is on social influence that is mediated by interactive technologies. The design of systems, interventions, and methods is sometimes both a means and an end.
I am a member of the MIT Sloan School of Management faculty, in the Marketing group. I am affiliated with the MIT Schwarzman College of Computing via the Institute for Data, Systems & Society, including its Statistics and Data Science Center, and the Initiative on the Digital Economy. (For the 2022–2023 academic year, I am on sabbatical.)
The principal subjects of my research are
- social interactions, contagion, and interventions in networks
- experimental design and inference in networks
- methods for causal inference
Multiple of these often end up appearing together in a single projects.
