Brian Walsh is senior economist in the Climate Change Group’s economics team. He manages applications of the Shock Waves and Unbreakable to inform long-term poverty eradication and decarbonization strategies. These models use stochastic microsimulations to integrate uncertainty, and predict resilience of the poor to shocks and transitions. Brian was previously a leader of the Global Facility for Disaster Reduction and Recovery (GFDRR) analytics team, where he studied disaster-induced poverty. Before joining the World Bank, Brian worked at the International Institute for Applied Systems Analysis on land use & carbon cycling, and he holds a PhD in particle physics.
