I'm a PhD student and NDSEG fellow at Tom Griffiths' Computational Cognitive Science Lab at Princeton University. I use computational modeling, behavioral experiments, and agent-based simulations to study how people make decisions. Often, this involves integrating individual-level models of cognition with distributed models of social dynamics. I am especially interested in using this framework to improve social network design and redesign choice architectures.

Before my PhD, I majored in both statistics and economics at the University of Toronto. During this time, I spent two summers at MIT working with Whitney Newey and Jerry Hausman on applied and theoretical econometrics, and one summer at Via as a data science intern. More recently, I interned at Microsoft Research and worked with Dan Goldstein and Jake Hofman to develop tools for out-of-sample forecasting.

I also enjoy data and model visualization and have recently started building electric scatter.
