Voss Postdoctoral Research Associate in Environment and Society
Dr. Allison Jacobel is an isotope geochemist whose work focuses on furthering our understanding of the climate system through the application of geochemical techniques and reconstruction of paleoclimatic records. She is particularly interested in glacial-interglacial transitions in climate and the mechanisms that amplify insolation forcing. Her past research includes studies examining shifts in the position of the Intertropical Convergence Zone, reconstructing changes in ocean ventilation, tracing past dust inputs to the equatorial Pacific Ocean, and using marine sediment cores to study abrupt climate change events in the North Atlantic. At Brown, Allison will be working with Tim Herbert to investigate the role of dust-driven iron fertilization in nitrogen fixation and carbon drawdown in the Pacific Ocean.
Jacobel earned her bachelor’s degree in Geology at Macalester College before beginning her graduate studies at Columbia University in the Department of Earth and Environmental Sciences. Since defending her dissertation she has been a postdoctoral research scientist at the Lamont-Doherty Earth Observatory in the division of geochemistry.
