Research Summary

Dr. Crowe is a geochemist who couples classical and molecular biological tools to geochemical techniques to study the co-evolution of life and Earth surface chemistry. Dr. Crowe’s current interests are in modern nitrogen cycling, the evolution of atmospheric oxygen through the Precambrian, and the role of Fe-based photosynthesis in early biological production and the deposition banded iron formations.
