I'm an Associate Research Scientist at the International Research Institute for Climate and Society (IRI) -part of the Earth Institute at Columbia University. I do research on subseasonal-to-decadal prediction, cross-timescale interference of climate modes, and how these topics can be used in model diagnostics, lightning and prediction of climate extremes. I also work on the development of climate services, and lead the Latin American component of the Columbia World Project "ACToday".
