I am a postdoctoral research fellow at the Center for the Management of Systemic Risk at Columbia University, funded by a James S. McDonnell Postdoctoral Fellowship in Studying Complex Systems.
During fall 2014, I am a visiting fellow at the Isaac Newton Institute for Mathematical Sciences at Cambridge University for the program Systemic Risk: Mathematical Modeling and Interdisciplinary Approaches.
My research aims to understand collective social phenomena, ranging from how people collaboratively create good ideas, to how the financial system undergoes crises, to how changes in behavior spread in a population. This work combines mathematical modeling with empirical studies, drawing from dynamical systems, networks, and probability as well as from statistics and data science.
