Sea Level And Ice


Dr. Helene Seroussi is a Scientist at Caltech's Jet Propulsion Laboratory in the Sea Level and Ice Group. Her research interests are focused on better understanding and explaining ongoing changes in the cryosphere, as well as reducing uncertainties in the ice sheet contribution to sea level rise using numerical modeling. She is interested in understanding the interactions of ice and climate by combining process studies, state-of-the-art numerical modeling with remote sensing and in situ data. She graduated from École Centrale Paris (France) in 2008 and received her PhD in 2011 in ice sheet systems numerical modeling and data assimilation from the same university. She Is a member of the scientific committee of ISMIP6 and co-chair of the MISOMIP project.
