Scientific interests

- Past climate dynamics

- Stable isotope geochemistry

- Marine and lacustrine archives

- Human-climate environment interactions

 

Determining the amount of cooling in the tropics during the last Ice Age has been a longstanding problem with large discrepancies between terrestrial and marine estimates. In my current project I intend to evaluate the magnitude of temperature change in the lowland Neotropics during the last Glacial by using two independent geochemical proxies: clumped isotope thermometry and tandem measurements of δ18O carbonate and gypsum hydration water.
