Director of Graduate Studies, Professor of Earth and Planetary Sciences
Primary research interests: Isotope geochemistry and historical geobiology; re-animating ancient ecosystems and ocean chemistry using stable isotope systems, chemical speciation techniques, modern microbial experiments (for calibration) and theoretical considerations.
The Salata Institute
The Salata Institute supports interdisciplinary research that leads to real-world action, including high-risk/high-reward projects by researchers already working in the climate area and new endeavors that make it easier for Harvard scholars, who have not worked on climate problems, to do so. Faculty interested in the Climate Research Clusters program should note an upcoming deadline for concepts on April 1, 2024.
