Our Team
Resilience is a team sport — it is built by people who understand science, systems, and the realities of decision-making and work together to create innovative and practical solutions. The Resilience Collaborative is led by a team of experts with experience in government, earth systems science, national security, risk outlooks, communications, and engaging with a wide range of partners. We bring different disciplines to the table with one shared goal: to catalyze decision-making and accelerate resilience action.
