Constantin's research focuses on cascading global catastrophic risk: how might small stressors trigger system failure that leads to much larger catastrophes? He is attacking this problem using a diversity of approaches, but with a particular grounding in nonlinear dynamics, Earth science, and the study of complex systems. He has a PhD in Earth, Atmospheric, and Planetary Sciences from MIT, where he worked on the intersection of these topics, and an undergraduate degree in Physics from Harvard College.
