Dr. Peter Crockford

My work explores the coevolution of life and the surface environment throughout Earth history. Examples of key questions that guide my research include: how much life has ever existed on the planet? What caused dramatic shifts in climate (i.e., snowball Earth glaciations) at the beginning and end of the Proterozoic eon? And how can we extract meaningful information about ancient seawater chemistry from highly altered sedimentary records? To help provide answers to these and many other questions my work combines isotope geochemistry, geobiology, field geology and insights from modern chemical oceanography.

I am currently recruiting PhD and MSc students to begin in the 2023/2024 academic year.
