Area(s): Geology, Paleoclimate

Research Summary:  Anne-Sofie C. Ahm is a Simons Foundation Postdoctoral Fellow working on numerical models of carbonate diagenesis and measurements of Ca, Mg, and Sr isotopes. She is intrigued by the fundamental processes that transform lithified sediments into rocks and how these processes affect the geochemical signature stored in the rock record of Earth history. In particular, she is interested in what the record of marine carbonate diagenesis - as revealed through the geochemical signature of Ca, Mg, and Sr isotopes - can tell us about ancient seawater chemistry and the origins of life on Earth.
