Research

A critical task of climate change research is to constrain the response of present-day ice reservoirs to climate warming and estimate their contribution to future sea-level rise. I work at the intersection between solid Earth geophysics and climate change science, studying the interactions between the solid Earth and climate systems. My research contributes to improving our understanding of past and future climate and ice mass changes by exploring the physics of sea-level changes and Earth deformation, accounting for this physics in state-of-the-art numerical models of ice-sheet evolution, and taking an integrated view of ice sheet 鈥� sea level 鈥� solid Earth interactions. The goals of my research are to aid in mitigating the impacts of global warming, improve the interpretation of geophysical observations of the past and present Earth system, and delineate the edges of the Earth鈥檚 resilience in the face of ongoing climate change
