Alexandra Jahn is an Associate Professor in the Department of Atmospheric and Oceanic Sciences and Fellow of the Institute of Arctic and Alpine Research. Alexandra likes everything to do with snow and ice, at work and in her free time. She is originally from Germany, where she studied Meteorology and earned a Masters degree, studying the climate of the past using models. Alexandra then earned a PhD in Atmospheric and Oceanic Sciences in Atmospheric and Oceanic Sciences from McGill University in Canada, studying the dynamics affecting the pathway of freshwater entering the Arctic Ocean. For her postdoctoral work, she studied Arctic sea ice projections at the National Center for Atmospheric Research (NCAR) in Boulder, CO, USA. She then returned to Paleoclimate research, to implement Carbon Isotopes into the ocean model of a climate model at NCAR. In 2015, she joined the University of Colorado as Assistant Professor, founding the Polar and Paleoclimate Modeling group.
