I study compound hydrological extremes as a PhD student in Earth and Environmental Sciences at Columbia University. I'm interested in how severe hazards will change under warming and the vulnerability of people and ecosystems to these changes.
At the intersection of drought and precipitation extremes is drought termination. Investigating the interplay between extreme precipitation and droughts, as compound events, is necessary to understand the physical processes that drive changes in these events and improve our ability to assess future impacts and risks. Like many compound events, drought termination is less well understood than its constituent components. I use large global climate model ensembles, experiments with the NASA GISS climate model, and observations to investigate how changes in precipitation affect drought termination in the context of future warming.
Floods are one of the most dangerous and deadly natural hazards. But not all floods are the same. Flood research, forecasting and response often concentrates on large-scale river floods at the expense of faster and often deadlier flash flood events. I am leading a systematic review of flash flood risk and response as part of the NASA-GEO Global Flash Flood Impact team to better understand the global state of flash flood research.
