Research Interests

Sedimentary rocks are a record of ancient environment, climate, and life.

That's why I study them, using field, laboratory, and computational techniques. I want to understand how climate and environment have affected life through its long history on this planet.

 In particular, I use the physical and chemical records of environment contained in rocks. As a member of the Bergmann lab at MIT, I use standard and clumped stable isotope analysis of carbonates to understand the ancient carbon cycle and ancient ocean temperatures. I also have experience using detrital zircons and LA-ICPMS to understand sediment provenance. 

My current focus on the Ediacaran period (635-541 Ma) has taken me around the globe to look at rocks dating from this climatically and biologically dynamic time where we see not only evidence for significant glaciation but also the emergence of the first macroscopic animals. I am currently working on sites from California, Newfoundland, Svalbard, and Oman. 

Collaborations with other faculty members at MIT have given me the opportunity to think about sediments (with the Perron lab) and ancient life (with the Fournier lab) using different perspectives and techniques.
