Past DLP Speakers 2015 – 2016

Elizabeth Cottrell

Dr. Elizabeth Cottrell is a curator in the Department of Mineral Sciences at the National Museum of Natural History, Smithsonian Institution where she serves as the Director of the Global Volcanism Program. Liz conducts experiments at high pressures and temperatures to understand the evolution of Earth’s mantle, from the time of planetary accretion and core formation to today. Currently she is focused on understanding how oxygen, hydrogen and carbon cycle between mantle reservoirs, and how this influences the petrogenesis of Earth’s crust and the deep carbon cycle. Liz received her PhD from Columbia University and was a postdoctoral fellow at the Geophysical Laboratory at Carnegie before joining the Smithsonian in 2007.

Bradley Hacker

Dr. Bradley Hacker is a Professor in the Department of Earth Science at UC Santa Barbara. His research focuses on field, laboratory, and theoretical study of tectonics using a combination of metamorphic petrology, structural geology, mineral physics, and geochronology. Particular topics of interest include continental subduction, continental collision, and ophiolite emplacement Applied tools are chiefly electron-backscatter diffraction, electron-probe microanalysis, and laser-ablation inductively-coupled-plasma mass spectrometry.

Beatrice Magnani

Dr. Beatrice Magnani is a seismologist at Southern Methodist University whose overarching research theme is the formation, evolution of continents, and continental dynamics. Dr. Magnani employs controlled-source seismology to image continents at a wide range of scales and resolutions, from the lithosphere to the near surface. Her research interests include the Eastern North American passive margin structure and evolution (ENAM Community Seismic Experiment Project), seismic oceanography, and GIA investigations in the Patagonian Andes.

Andy Nyblade

Dr. Andy Nyblade is Professor of Geosciences at Penn State University. He uses seismic recordings of earthquakes to interrogate earth structure in continental settings to understand deep earth processes linked to rifting, plateau uplift, volcanism, basin evolution, mountain building, crustal genesis and craton formation. For the past 10 years, he has led the AfricaArray initiative to build science capacity in Africa and the U.S. through coupled data gathering, research and education programs. He has worked extensively throughout eastern and southern Africa for over 25 years, where much of his research has focused on imaging the African superplume.

Robert Stern

Dr. Robert J. Stern is Professor of Geosciences at the University of Texas at Dallas. His research focuses on three complementary themes: 1) How modern arc crust forms above subductions zones and evolves into true continental crust; 2) How new subduction zones form; and 3) When and why Plate Tectonics began on Earth. He and his students and collaborators emphasize geochemical and isotopic data sets to investigate examples around the globe, both on land and beneath the sea. Active areas of study include modern examples of arc and backarc basin igneous activity in the Izu-Bonin-Mariana, Japan, Central American and Aleutian arcs, and ancient examples in Afro-Arabia and Iran.

Laura Wallace

Dr. Laura Wallace is a Research Scientist at the University of Texas Institute for Geophysics. Laura uses geodetic methods to investigate deformation of the Earth’s crust at plate boundaries, with a particular focus on subduction zones. She undertakes research at various locations in the western Pacific. She is particularly interested in understanding the physical mechanisms that control subduction thrust earthquakes and slow slip events. She is currently leading a large-scale international project to deploy ocean bottom seismometers and seafloor geodetic instruments to investigate slow slip events offshore New Zealand. Prior to her arrival at the University of Texas, Laura was a research scientist at GNS Science in New Zealand for nearly a decade.
