Frankie Pavia is an isotope geochemist who is interested in devising and applying new techniques to study the modern and past evolution of Earth’s climate and carbon cycle. His research uses radioactive isotopic tracers as fingerprints of how quickly Earth system processes occur. Frankie arrived at UW in early 2024 and is building a research program to study many facets of Earth’s climate, including but not limited to particle aggregation processes and carbon degradation in seawater, changes in sea ice coverage and ice sheet melt in the geologic past, and the weathering of mantle rocks at the seafloor.
