Geosciences

Robert Liebermann is former Chair of the Department of Geosciences and Associate Director of the Mineral Physics Institute. He also is President of the nationwide Consortium for Material Properties Research in Earth Sciences (COMPRES), which is based at Stony Brook. COMPRES conducts research focus on “deep earthquakes” occurring in the Earth’s deep mantle at depths greater than 400 miles. He is a member of the American Geophyscial Union, the Mineralogical Society of America, and the Seismological Society of America.

Specific areas of expertise: Deep earthquakes. Temperature, pressure, and water storage in the Earth’s deep mantle.

Scott McLennan, Ph.D., is Professor of Geochemistry and Chair of the Department of Geosciences. His research is focused is directed toward gaining a better understanding of the chemical composition and evolution of the continental crust, and plate tectonic associations of ancient sedimentary sequences. He also was selected by NASA to participate in the Mars Exploration Rover Mission and was part of the team at the Jet Propulsion Laboratory which analyzed the data sent back to Earth. Since 1998, he has research has focused on analyzing geochemical data returned from the surface of Mars to understand the nature of the sedimentary processes that have operated on that planet during its history.

Specific areas of expertise: Geochemistry of sedimentary rocks. Ancient sedimentary sequences. Ancient climates.

Teng-fong Wong is Chair of the Department of Geosciences and Professor of Geophysics. He obtained his Sc.B. degree from Brown University, M.S. from Harvard University, and Ph.D. from Massachusetts Institute of Technology. His research interest is in rock mechanics and fluid flow, with focus on earthquake mechanics, energy resources and environmental applications. He also has been widely cited as an expert on tsunamis and their causes. His research is funded by the Department of Energy, National Science Foundation and USGS/National Earthquake Hazards Reduction Program. Professor Wong is on the Advisory Board of the San Andreas Fault Observatory at Depth.

Specific areas of expertise: Rock mechanics and fluid flow. Earthquake mechanics.

Gilbert Hanson, Ph.D., is a Professor in the Department of Geosciences and an expert on the geological history and topography of Long Island. He has developed new geochronological approaches for dating geologic events and has used major and trace elements, radiogenic isotopes, and radiometric dating for evaluating processes contributing to the evolution of the crust and mantle. He is a member of the Long Island Groundwater Institute and his present research focuses on groundwater geochemistry and the geology of Long Island.

Specific areas of expertise: Geochemistry and isotope geology.
