I am a social scientist and statistician studying social influence that is mediated, amplified, or directed by interactive technologies. The design of new interactions, interventions, and methods is sometimes both a means and an end. I recently joined the faculty of the MIT Sloan School of Management in the Marketing group. Until recently, I worked on the Facebook Data Science Team.

The principal subjects of my research are

  1. social interactions and influence through communication technologies
  2. persuasive strategies implemented with interactive technologies
  3. applied statistics and causal inference, especially for 1 and 2

Within these areas, I have worked on peer effects in networks, the spread of rumors and information, design of experiments in networks, high-dimensional methods for observational causal inference, mobile persuasive technologies, self-disclosure and sharing behaviors, multi-armed bandit problems, and persuasion profiling.

In 2012 I completed my PhD in Clifford Nass’s CHIMe Lab at Stanford University. I was previously a member of the research staff at Nokia Research Center, Palo Alto. Before joining Nokia, I worked with BJ Fogg on research in mobile persuasive technologies in the Stanford Persuasive Technology Lab and worked at Yahoo! Research Berkeley, designing and studying mobile photo sharing apps and services.

I try to use my blog, Ready-to-hand, and Twitter to share new ideas and report on research in an immediate and less formal way than scholarly publications.
