Research Interests
I use sedimentary records of Earth history to understand how the Arctic will change in a warmer, wetter, and human-dominated world. My research currently focuses on how Holocene climate impacts glaciers, shrubs, and carbon cycling in lake and marine environments. To do so, I develop and use geochemical tools based on lipids, stable isotopes, and ancient DNA, and incorporate new geochronological, data science, and modeling approaches. These data underpin predictive climate models, conservation efforts, and carbon dioxide removal strategies.
