I'm a third-year 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 deal with uncertainty and complexity in their everyday decision making. 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 was an undergraduate at the University of Toronto, where I majored in both statistics and economics and minored in mathematics. 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.

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