  • Brief Bio

    Isabel Nias joined the Cryospheric Sciences Laboratory in March 2018 as a postdoctoral associate in the NASA Sea Level Change Team. Isabel comes from the University of Bristol, where she completed her PhD in glaciology, where her research involved modeling the ice streams of the Amundsen Sea Embayment in West Antarctica, with a particular focus on grounding line dynamics. At Goddard, Isabel is using the Ice Sheet System Model (ISSM) to constrain the committed sea level contribution from the Greenland Ice Sheet.

    Research Interests

    ice sheet dynamics; ice flow modeling; sea level projections; model-data comparison; grounding line migration; Greenland; West Antarctica

    Positions/Employment

    12/2017 - 3/2018

    Field assistant

    University of Leeds, Antarctica

    Assisted with the collection of sea ice measurements (radar, salinity, density) on a scientific cruise (RRS Ernest Shackleton) in the Weddell Sea, Antarctica
