Postdoc position

High-resolution climate and hydrology projections for the Rocky Mountains

Our group at Cornell University is looking for a Postdoctoral Associate to investigate downscaled climate projections from the CESM2 Large Ensemble.

The overarching motivation is to assess the time and warming level at which snow-related hydrology metrics in the Rocky Mountains emerge from their historical variability, as well as better understand associated uncertainties. The results will inform stakeholders about when existing infrastructure and water management strategies are likely to become inadequate given their design based on historical expectations of climate variability. 

The postdoctoral researcher will be supervised by Prof. Flavio Lehner and also work with Dr. Keith Musselman’s group at the University of Colorado Boulder. The effort will analyze and integrate observational and climate model datasets, specifically CESM2 Large Ensemble simulations downscaled with WRF. There will be further collaborations with Dr. Julie Vano from the Aspen Global Change Institute (AGCI), who will facilitate disemination of the results to a wide range of stakeholders.

The position is funded by NSF and is based at Cornell University in Ithaca, NY. There will be support for conferences and travel to collaborate in-person with project partners in Boulder and AGCI. The successful candidate would join an active community of postdocs and personal development opportunities at Cornell (see
