Sea level, ice sheets
& Earth dynamics.
Research on past and future sea-level change, ice-sheet stability, and the dynamics of the solid Earth.
Understanding how Earth changes
— through time and space
I'm an Associate Professor at Columbia University and part of the Seismology, Geology and Tectonophysics Division at Lamont-Doherty Earth Observatory. I study how Earth has changed in the past, how it is changing today, and how it may change in the future, with a focus on sea level, ice sheets, and the dynamics of Earth's interior. I use geophysical modeling, conduct geological fieldwork, and engage with communities to understand how our work impacts society.

HISEAS
HISEAS uses the Last Interglacial as a natural experiment to determine how much and why Greenland and Antarctic ice sheets melted, combining paleoclimate, sea-level, and Earth-system modeling.
Visit projectMAGIC
MAGIC combines historical glacier reconstructions, satellite observations, glacier modeling, and AI to improve predictions of mountain-glacier melt and its contribution to sea-level change.
Visit projectMINERALS
MINERALS connects mineral physics, seismology, and geodynamics to build a predictive framework linking mineral properties at atomic scales to the structure and dynamics of Earth’s deep interior.
Visit projectSWAIS2C
SWAIS2C uses geological records from beneath the Ross Ice Shelf to determine how the West Antarctic Ice Sheet responded to past warming and improve projections of future sea-level rise.
Visit projectGreenland Rising
Greenland Rising combined coastal mapping, sea-level observations, modeling, and community partnerships to understand how a changing Greenland Ice Sheet affects natural, social, and built environments.
