Welcome to my homepage!

I'm an Associate Professor at Columbia University and part of the Seismology, Geology and Tectonophysics Division of Lamont-Doherty Earth Observatory. In my research, I study sea level changes ranging from the past glacial cycles to Millions of years ago in order to infer ice mass changes and ice sheet stability as well as constrain the Earth's rheology. My work also deals with better understanding and constraining modern and future sea level change. I'm also interested in geodynamic and plate tectonic problems dealing with plate driving forces and dynamics of the Earth's deep interior.

My CV can be found here (last updated 3/2025).
