David A. Hodell

David A. Hodell, FRS (born 1958) is a British–American geologist and paleoclimatologist. In October 2008, Hodell was appointed to the position of Woodwardian Professor of Geology at the University of Cambridge in the United Kingdom, where he is also a fellow of Clare College. He is a dual citizen of the United Kingdom and the United States. He is also the Director of the [https://godwinlab.esc.cam.ac.uk/ Godwin Laboratory for Palaeoclimate Research]. Previously, he taught at the University of Florida from 1986–2008, earning the rank of full professor in geological sciences. Hodell was also the director of the Stable Isotope Laboratory from 1996–2008. Hodell earned his Ph.D. in 1986 in oceanography from the [https://web.uri.edu/gso/ Graduate School of Oceanography], University of Rhode Island after earning his bachelor of arts in 1980 in geology from the University of Vermont.

He is a geochemist who studies Earth’s past climate. He has led many drilling expeditions of the International Ocean Discovery Program (IODP) and field excursions to collect marine and lake sediment cores and speleothems for palaeoclimate reconstructions. His research has demonstrated how past climate change affected ancient civilisations, such as the Maya and Indus Valley. Research by Hodell, Brenner, Curtis and Guilderson was instrumental in rethinking the Maya Collapse. Climate data derived from core samples retrieved from closed lake systems in the Mexico's Yucátan and Guatemala showed a period of extensive drought. In 1995, Hodell, Curtis and Brenner published a paleoclimate record from Lake Chichancanab on the Yucatán Peninsula that showed an intense, protracted drought occurred in the 9th century AD and coincided with the Classic Maya collapse. He has also made key contributions to understanding the Ice Age cycles of the Quaternary and their relationship to Earth’s orbit—for which he was awarded the Milutin Milanković Medal of the European Geophysical Union. More recent work has focused on the causes of rapid (millennial) climatic changes during the Quaternary using the extraordinary sedimentary archive preserved below the seafloor of the Iberian margin Provided by Wikipedia
