About


Our mission is to improve our understanding of the response of the ice sheets in a changing climate, their interactions with the other components of the climate system, and provide reliable projections of sea level rise. We combine different methods such as numerical modeling, remote sensing, laboratory experiments and field work to address these questions.

Who are we?

Fellowships


Visiting Graduate student fellowships:We are pleased to announce the Evans Family Short-Term Graduate Student Fellowship Program at Dartmouth College. We are soliciting applications from current graduate students that will come to Hanover, New Hampshire for 3 to 6 months to work on a project focused on polar science with a Dartmouth faculty member. We anticipate supporting up to 3 student visitors in 2024 and potential hosts include faculty from the Thayer School of Engineering, Earth Sciences, Math, Arctic Studies, and collaborators at the Cold Regions Research and Engineering Laboratory. The fellowship will cover the cost of travel and lodging up to $10,000 for 3 months or up to $15,000 for 6 months. Applications are due November 1st with notifications sent by December 1st for research visits in the Spring, Summer, or Fall of 2024. The application form is linked here and includes a 1-page research statement (that can be crafted in conjunction with your faculty host). If there are any general questions before the application due date, feel free to reach out to colin.r.meyer@dartmouth.edu or mathieu.morlighem@dartmouth.edu. Dartmouth College is an equal opportunity employer with a strong commitment to diversity and inclusion. We prohibit discrimination on the basis of race, color, religion, sex, age, national origin, sexual orientation, gender identity or expression, disability, veteran status, marital status, or any other legally protected status. In that spirit, we are particularly interested in receiving applications from individuals with a broad spectrum of experience and identity.

Sabbatical support (for faculty and researchers): contact us if you would like to spend 6 months or more with us. More information will be posted later.
