Helene Seroussi (CV)

Before joining the Thayer School of Engineering at Dartmouth in 2021, I was a scientist at the Jet Propulsion Laboratory in Pasadena, CA, for 10 years. My 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 by combining process studies, state-of-the-art numerical modeling with remote sensing and in situ data. I was born and raised in Paris, France, and graduated from École Centrale Paris in 2008 and received my PhD in 2011 from the same university. I received the NASA Early Career Achievement Medal and the JPL Charles Elachi award in 2019 and the AGU Early Career Award in 2020. I am a member of the NASA Sea Level Change Team (N-SLCT), and a member of the scientific steering committee of the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6) and the WCRP Climate and Cryosphere (CliC).

Jessica Badgeley

Jessica Badgeley received her Ph.D. in Earth and Space Sciences from the University of Washington in Seattle. Her research has focused on the evolution of polar climate and ice sheets from the last glacial maximum to present. She is now transitioning to studying historical and future time periods. She is generally interested in combining observations and numerical models as a tool for understanding ice-climate interactions.


Tobias Harvey

Tobias is a graduate student at Dartmouth College.

James McMahan

I am a Ph.D student at Dartmouth College in the Ice and Sea Lab. Prior to Dartmouth, I worked at Los
Alamos National Laboratory in the Field Instrument Deployments and Operations team, where I helped
deploy and operate remote climate observatories. From this work, I gained the appreciation for the challenge involved in gathering both spatially and temporally varying data in remote and hostile locations.
This gave me a desire to come to Dartmouth where I could combine numerical modeling with robotics and
sensor deployment. To this end, my research is a combination of numerical modeling of ice-ocean interaction in Greenland and developing a novel Autonomous Underwater Vehicle to gather data in Greenland’s glacial fjords.

Hyoeun Shim

I am a Ph. D student in the Ice and Sea Lab group. I graduated with a M.S in computational science and engineering at Yonsei University, South Korea. Before joining Ice and Sea Lab, I had studied particle-laden turbulence using direct numerical simulations. My primary research interest is ice ocean interactions, with a particular focus on Antarctica to better estimate ice sheet contribution to future sea level rise.
