Current Research

I am interested in the geological record of marine carbonates and the information it holds about past climate, oceanic chemistry, and geochemical cycles. In particular, I use calcium isotopes along with major and trace element chemistry to interpret ancient environments and processes. I hope to investigate intervals of environmental change, carbon cycle perturbations, and evolutionary developments in Earth history, along with examples of modern settings. I am also interested in the geochemistry of evaporite formations and the records they contain about seawater chemistry. 

Previous Study

I completed my doctoral thesis in 2012 at the University of Oxford (UK), where I was supervised by Gideon Henderson and Hugh Jenkyns. I received my undergraduate degree in Earth and Planetary Sciences from Harvard College in 2008, where I wrote an honors thesis with Daniel Schrag and Kate Dennis.
