About Noah John Planavsky's Work
I study the connections between the evolution of Earth-system processes, biological innovation, and ecosystem change—foremost in Earth’s early history. My research integrates field, petrographic, and geochemical work. The protracted rise of oxygen over several billion years dramatically changed Earth’s surface environments. However, our current picture of Earth’s redox evolution is still painted with only broad strokes. A central theme of my research program has been trying to piece together the history and effects of Earth’s oxygenation. With that end goal in mind, my research group is currently working on coupling paleoredox proxies, calibrating novel metal isotopes systems in modern aqueous systems, and untangling the distribution and diagenetic history of traces metals in sedimentary rocks.
