Rob DeConto
Professor of Geosciences
University Massachusetts, Amherst, Massachusetts

Rob DeConto creates and tests computer models of Earth’s climate and studies how climate change influences ice sheets. He applies his models to both past and future times. He focuses primarily on polar regions and how the ice sheets in Greenland and Antarctica respond to increased carbon dioxide in the atmosphere.


Paul Hearty
Associate Professor of Environmental Studies
University of North Carolina at Wilmington, North Carolina

Paul Hearty studies periods of past high sea level. He is especially interested in interglacial periods, the warm intervals between the recent ice ages, that occurred periodically over the last half a million years.  His research consists principally of identifying stratigraphic and sedimentary evidence of past seashores, such as fossil corals, shells, and the petrified remains of paleo beach shorelines.


Jeremy Inglis
US Operations Engineer, Isotopx
Chapel Hill, North Carolina

Jeremy Inglis runs the US technical and service branch of Isotopx, a British producer of high precision mass spectrometers.  His specialty is in using mass spectrometers to study the chemistry and age of geological samples. He has developed techniques to use thermo isotope mass spectrometers (TIMS) to date geologic samples.


Jerry X. Mitrovica
Professor of Earth and Planetary Sciences
Harvard University, Cambridge, Massachusetts

Jerry Mitrovica creates numerical and theoretical models that predict how oceans and crust respond to changes both on Earth’s surface and deep inside the planet’s interior. Jerry has developed state-of-the-art models of sea-level change caused by the growth and decay of ice sheets as well as by movement of mass within the Earth’s interior.


Michael O’Leary
Lecturer in Geology
Curtin University, Perth, Australia

Michael O’Leary studies past sea level during periods of known climate instability. He also researches the response of tropical coastlines, such as low coral reef-islands, to future sea level rise.

David Pollard
Senior Scientist 

Earth and Environmental Systems Institute

Pennsylvania State University, University Park, Pennsylvania

David Pollard creates and tests computer models of Earth’s climate and its interactions with the ocean, vegetation and ice sheets. Some of his research involves applying computer models to the study of past climates and polar ice sheets.


Maureen Raymo
Research Professor
Lamont-Doherty Earth Observatory
Columbia University, Palisades, New York

Maureen Raymo studies the history and causes of climate change in Earth’s past. She founded the Pliomax project, a research effort aimed at reducing uncertainty in estimates of sea level during the Pliocene era, about 3 million years ago. She is also the Director of the Lamont-Doherty Core Repository at the Lamont-Doherty Earth Observatory.

Alessio Rovere
Post Doctoral Fellow
Lamont-Doherty Earth Observatory
Columbia University, Palisades, New York

Alessio Rovere is an expert on how geological forces cause changes in landforms and in geographic information systems.  He is creating a global database of geological markers of high stands of sea level over the last several million years, as measured by geologists around the world.
