Don works on airborne and satellite-based geophysics of ice with a focus on Antarctica and the icy moons of Jupiter.

Ginny works on understanding the processes that drive ice sheet dynamics with a focus on ice-bed and ice-ocean interactions. She uses space and in-situ observations to complement models.

Ann focuses on the development of Interferometric Synthetic Aperture Radar (InSAR) techniques for studying changes in the Earth’s surface and subsurface including permafrost hydrology and the carbon cycle.

Cyril studies the properties of surfaces and ice-ocean interfaces on Earth to bridge them with planetary radar observations in order to better understand the cryospheres of other worlds.

Ruthie is joining the JSG in Fall 2024! Ruthie integrates geologic data and numerical models to reconstruct Antarctic climate and ice sheet dynamics during past warm periods.

The Computational Research in Ice and Ocean group (CRIOS) applies advanced computational methods to improve understanding of the role of the ocean, sea ice and ice sheets in the climate system.

Blair’s research focuses on turbulence examined through laboratory experiments. She investigates ice-ocean melting processes in a novel lab setting to test the idea that turbulence drives terminus melt.

Benjamin is interested in past archives of the Earth system and what they can teach us about the future. He investigates this with numerical ice-sheet and climate models integrated with geologic archives.

Lori runs the 3D Geospatial Lab where she uses remote sensing observations to image the Earth in 3D. These data underpin Earth exploration that permit us to quantify our changing environment.

An’s research focuses on understanding the coupled ocean sea-ice system through observations and numerical simulations.

Helen works on model-data synthesis for the Arctic and subpolar North Atlantic. She is interested in detecting climate signals within existing ocean datasets to support monitoring of the current and future ocean state.

Kiki is interested in ice-ocean interactions and small scale mixing and transport processes in the ocean, with a focus on the Arctic ocean.

Liang’s cryosphere research is focused on the representation of snow, frozen soil, permafrost, and solid precipitation in hydrology, weather and climate models. He leads the Land Environment and Atmospheric Dynamics group.

Duncan’s work focuses on the search for ancient ice in Antarctica, the geologic controls on the evolution of the ice sheets, and determining the subglacial interface in Antarctica.

Omar works on advanced mathematical, computational, and statistical theory and algorithms for complex high-dimensional inverse and optimization problems including ice sheet dynamics and ice-ocean interactions.
