Our Team
Describe your team here.
Kelly Fenton-Samuels is a Ph.D. student in the Department of Earth and Environmental Sciences at Columbia University, collaborating with the LDEO PAST Group and the LDEO Argon Geochronology for the Earth Sciences (AGES) Lab. Her current research reconstructs ice-rafted debris flux and provenance to examine Antarctic Ice Sheet stability during the late Neogene and Quaternary. This work enhances our understanding of the Earth's climate system and informs predictions of sea-level change in a rapidly warming world. She aspires to use her geochemistry background to pursue a research career investigating paleoclimate through laboratory techniques.
Joanna studies Greenland's glacial history and how the ice sheet has interacted with the ocean on geologic timescales. For her postdoctoral research, Joanna is studying the paleoenvironmental conditions in Baffin Bay before, during, and after the Last Glacial Maximum.
Gabriel is working on high-resolution stratigraphy through discrete time intervals in Southern Ocean sediments and testing new instruments/methods at the Paleomagnetics Lab.
Dennis V. Kent is Adjunct Senior Research Scientist at Lamont-Doherty Earth Observatory of Columbia University and Board of Governors Professor Emeritus at Rutgers University. He is an author of more than 300 journal and book articles with nearly 40,000 citations and an h-index of over 90 on Google Scholar dealing with paleogeography, paleoclimate and the long-term carbon cycle, polar wander, geomagnetic paleosecular variation and the tempo of polarity reversals, and other aspects of Earth magnetism.
Kent has served as a member and a chair of the governing boards of the Joint Oceanographic Institutions and Integrated Ocean Drilling Program Management International; as elected president of the Geomagnetism and Paleomagnetism Section of AGU; as elected member-at-large of the section on Geology and Geography of AAAS; and on the editorial advisory board of the Earth and Planetary Science Letters.

Brendan Reilly is an Associate Research Professor at Columbia University's Lamont-Doherty Earth Observatory (LDEO). He is Director of the Lamont-Doherty Core Repository (LDCR), one of the largest collections of seafloor samples in the world. In this role, he helps care for and make accessible a globally important archive of marine sediments used by researchers studying Earth’s climate and ocean history. He also leads LDEO's Paleomagnetics and Stratigraphy (PAST) Group and Paleomagnetics Laboratory.
As a seagoing geological oceanographer, he studies how seafloor landscapes and marine sediments record Earth's history. Much of his work focuses on reconstructing past changes in ice sheets in Greenland and Antarctica using marine sediment cores. He specializes in paleomagnetism, the study of Earth’s ancient magnetic field preserved in rocks and sediments, which provides a powerful framework for dating sediments and linking climate records from different parts of the world.
