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. I am looking for jobs to start in 2016.
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.
Lately I have been working on fragility and economic development. In collaboration with economists, I have been studying a new model of how dysfunction in an economy can be contagious and can result in poverty traps, cycles, and and surprising responses to seemingly sensible policies. Stay tuned for a working paper.
