Brian Beaty

I’m a PhD student working with Prof. Noah Planavsky and Prof. Lidya Tarhan. I’m broadly interested in the coevolution of life, climate, and chemical cycles across Earth history, and how these interactions can inform our understanding of modern environmental changes. Most of my work involves geochemical analyses of sedimentary rocks to explore changes to Earth’s surface environments across a range of timescales, from geologically-rapid climate events to the entire scale of Earth’s history (billions of years). Current projects include investigating the nature of chemical weathering on land in the Precambrian, and the role of animal-sediment interactions (bioturbation) in shaping ocean chemistry across the Permian-Triassic mass extinction.
