Suzanne Birner successfully defended her PhD thesis, “Variations in the Oxygen Fugacity of the Upper Mantle“. Congratulations Dr. Birner!
Katie Kumamoto successfully defended her PhD thesis, “Exploring the Rheological Properties of the Upper Mantle: From the Field to the Laboratory”. Congratulations Dr. Kumamoto!
Research by Katie Kumamoto, Jessica Warren, and colleagues on the strength of olivine has been published in Science Advances. Our research suggests that tectonic plates are weaker than previously thought due to a size effect in olivine, the most abundant mineral in the Earth’s mantle. The article is summarized by Karen Roberts in this UDaily […]
Kendra Lynn has joined the Mantle Processes Group as a postdoctoral scientist. Kendra received her PhD in Geology and Geophysics from the University of Hawai’i. She worked with Mike Garcia on compositional zoning in olivine from Kilauea tephras, focusing on diffusion chronometry as a tool for investigating magmatic processes. At the University of Delaware, Kendra […]
Cecile Prigent has joined the Mantle Processes Group as a postdoctoral scientist. Cecile received her PhD from the Universite Grenoble-Alpes, France, working with Stephane Guillot and Philippe Agard on the interaction of subduction fluids with peridotites in the Oman Ophiolite. Her research focus is on the feedbacks between ductile deformation and fluid circulation.
Suzanne’s presentation at the 2016 AGU Fall Meeting has been awarded the GeoPRISMS Prize for Outstanding Student Oral Presentation: Birner, Cottrell, Warren, Kelley, and Davis, 2016. Records of upper mantle oxygen fugacity gleaned from high-density sampling of basalts and peridotites at ultraslow ridges, AGU Fall Meeting, T32A-05. Congratulations Suzanne!!
Fred Davis’s paper in American Mineralogist is now published and open access: Davis, F.A., E. Cottrell, S.K. Birner, J.M. Warren, and O.G. Lopez, 2017. Revisiting the electron microprobe method of spinel-olivine-orthopyroxene oxybarometry applied to spinel peridotites, American Mineralogist, 102, 421-435, doi:10.2138/am-2017-5823.
Katie’s presentation at the 2016 AGU Fall Meeting has been awarded an AGU Outstanding Student Paper Award: Kumamoto, Wallis, Hansen, Armstrong, Wilkinson, and Warren, 2016. Olivine Strength in the Low-Temperature Plasticity Regime Measured Via Spherical Nanoindentation, AGU Fall Meeting, MR32A-05. Congratulations Katie!!
In an open access article published in the Proceedings of the National Academy of Sciences, Lars Hansen, Jessica Warren, and Chao Qi use experiments on olivine aggregates to show that the base of the lithosphere is best represented by thermal models that predict a gradational boundary. The deformation experiments indicate that changes in seismic anisotropy […]
Following the successful completion of her PhD at Stanford University, Megan D’Errico is moving to San Diego State University for a postdoctoral position in science education. Good luck Megan!
