The Vecchi Research Group focuses on climate science and extreme weather events, hurricanes, mechanisms of precipitation variability and change, ocean-atmosphere interaction, and detection and attribution. Their research topics are listed below. The faculty lead is Gabriel Vecchi, Professor of Geosciences at the Department of Geosciences.

Gabriel Vecchi is also the director of High Meadows Environmental Institute (HMEI), he is co-director the Cooperative Institute for Modeling the Earth System, a collaboration between Princeton and the Geophysical Fluid Dynamics Laboratory. Vecchi is director of HMEI’s Climate and Energy Challenge as well.
