She is a polar physical oceanographer primarily focussing on the transport of heat by global deep waters and their interaction with the cryosphere. To study them she uses mostly global coupled models, but also goes at sea to collect new measurements. She completed her PhD in 2015 from the University of East Anglia, UK, and before that studied hydrodynamics engineering in France. She tweets as @ClnHz and blogs on PolarFever when at sea.
