Graduate Student Opportunities

Nicholas Christie-Blick:  ncb@ldeo.columbia.edu  Recruiting graduate students to work in diverse aspects of sedimentation processes, crustal deformation and deep-time Earth history. Opportunities exist for new field-based structural, stratigraphic, geochronological and thermochronological studies in the central Basin and Range Province of eastern California, southern Nevada and western Arizona; sequence stratigraphic studies aimed at the role of deformation in modulating sedimentary cyclicity; and studies of an array of issues in Neoproterozoic geology.  http://www.ldeo.columbia.edu/~ncb/

James Davisjdavis@ldeo.columbia.edu  Seeks graduate students for research involving the application of positional and physical geodesy using space-based and satellite techniques to a wide range of studies focused on geophysics, climate, ice sheets, glacier dynamics and kinematics, and the atmosphere. Opportunities also exist for research into new technologies aimed at the improvement of the accuracy of satellite and ground-based geodetic systems and the broadening of their applications.  http://www.ldeo.columbia.edu/user/davis

Goran Ekstromekstrom@ldeo.columbia.edu  Seeks students to work on the development and application of techniques to image the interior of the Earth on global and regional scales using seismic data. Additional opportunities exist for students interested in the analysis of earthquake sources, including exotic events associated with volcanos, landslides, and glaciers.   http://www.ldeo.columbia.edu/user/ekstrom

James Gahertygaherty@ldeo.columbia.edu  Uses natural-source seismic imaging to gain a better understanding of the dynamic processes in the mantle that drive surface deformation and volcanism. We are exploring tremendous new data from EarthScope, as well as data that we collect in innovative land-and-sea-going field experiments. Current projects include evaluating the fundamental processes underlying the formation of oceanic plates; the role of faulting and magmatism in the development of new plate boundaries in East Africa; the influence of plate formation and evolution on seismogenesis in the Cascadia subduction zone; and imaging magmatic processes across the North American continent.   http://www.ldeo.columbia.edu/~gaherty/

Ben Holtzmanbenh@ldeo.columbia.edu  Projects entail studies of the rheological properties of rocks (mineral and rock physics) across the wide range of thermodynamic conditions in plate boundaries from the seismogenic zone to the sources of melting in the asthenosphere. Several of my projects involve close collaboration with observational seismologists working on upper mantle structure in actively deforming plate boundaries. Other projects involve more detailed study of deformation processes in experiments and nature, involving close collaboration with experimentalists and theoretical mechanicians. While I mostly now work on developing the analytical tools for interpretation of seismic measurements and of deformation experiments and your projects would be part of these efforts, we would build an observational aspect to your thesis project, as observational skills are critical for building intuition for natural processes.  The observational aspect of your project could range from using sound to study seismic processes to using electron microscopes to study textures in deformed rocks. It is likely that your thesis would partly involve collaboration on both observational and theoretical/analytical aspects of a problem, but the design of the problem would take form as your interests develop over the first two years.  http://www.ldeo.columbia.edu/user/benh

Won-Young Kimwykim@ldeo.columbia.edu  Operates seismographic networks in the northeastern United States and abroad.  I am working on detection, location and identification of earthquakes and underground nuclear tests by analyzing local and regional seismic data.  Current projects includes earthquake studies in Bangladesh -- a tectonically-active delta (i.e., Ganges-Bramaputra-Meghna Delta); and seismic decoupling experiment in New Hampshire, USA.   Graduate students interested in monitoring earthquakes, instrumentation, quantification of sources and characterization of moderate sized earthquakes in the stable continental regions are encouraged to contact me. Students interested in the current projects are also welcome to join us.   http://www.ldeo.columbia.edu/~wykim/

Einat Leveinatlev@ldeo.columbia.edu  I study the dynamics of volcanic processes, and in particular the controls on lava flow emplacement. I employ a wide range of tools, including numerical modeling, laboratory experiments, image analysis and field observations. I also use similar tools to study large scale flows in the Earth's mantle. Students interested in lava, magma, or volcanoes, are invited to contact me. More information can be found at:   http://www.ldeo.columbia.edu/~einatlev/

Bill Menkemenke@ldeo.columbia.edu  Seeks graduate students for research on the seismic imaging of the earth, and especially its lithosphere, including tectonic features such as active faults, volcanoes and ancient sutures. Projects focused on data processing and interpretation interpretation, algorithm development and fieldwork are all available.  http://www.ldeo.columbia.edu/user/menke

 Meredith Nettlesnettles@ldeo.columbia.edu   Seeks students interested in earthquake source processes, including seismogenesis in glacier and ice-sheet systems, and studies of upper-mantle seismic velocity structure. Studies currently underway include a multidisciplinary investigation of earthquake source processes and glacier dynamics at major outlet glaciers, primarily in Greenland; the investigation of unusual seismic sources on continental margins; and surface-wave studies of the continental upper mantle, globally and in North America and Greenland.  http://www.ldeo.columbia.edu/~nettles/

Paul Richardsrichards@ldeo.columbia.edu  I am generally interested in all facets of the subject matter described in my “Quantitative Seismology” textbook with Kei Aki. But my main interest now is in “Precision Seismology” and in particular in one of the oldest problems in seismology, namely: how can we best locate, and characterize, earthquakes and explosions? Hundreds of seismic events are detected each day, and at last we have methods to locate most of them much more accurately than hitherto. This has been demonstrated with many special studies that focus on particular regions of high seismic activity. I have a multi-year new collaborative project to do this work on a global scale, using state-of-the-art database management and multi-processor computation. There are many science applications, and I welcome student involvement.   http://www.ldeo.columbia.edu/user/richards

Heather Savagehsavage@ldeo.columbia.edu  My research focuses on earthquakes and faults.  Some of the questions I am most interested in revolve around how earthquakes get started and what evidence they leave behind in the rock record, such as: At what stresses do faults fail?  How do faults grow from little faults to big faults? Do failure strength and triggering susceptibility change as a fault matures?  Can we assess from the geologic record the seismic activity of an exhumed fault? I address these questions through friction experiments in the Rock Mechanics lab at Lamont, as well as through field work and modeling.  http://www.ldeo.columbia.edu/~hsavage/Site/Welcome.html

Bruce Shawshaw@ldeo.columbia.edu  I am interested in the physics of earthquakes, the dynamics of the source, the growth and mechanics of faults. More generally problems concerning nonlinear dynamics in the earth sciences. Opportunities for interested students.   http://www.ldeo.columbia.edu/~shaw/

Felix Waldhauserfelixw@ldeo.columbia.edu  Works on the development and application of high-precision earthquake location and analysis methods to study the structure and mechanics of active faults, the spatio-temporal evolution of seismicity, and the physical processes underlying seismic failure. Opportunities for students and postdocs exist in working on global-scale applications to study subduction zones world-wide, in developing real-time applications for high-resolution monitoring and analysis of changes in seismogenic properties, and in exploring an extremely rich OBS data set to study tectonic and magmatic process on the fast-spreading East Pacific Rise.  http://www.ldeo.columbia.edu/~felixw/

Spahr Webbscw@ldeo.columbia.edu  My group studies the structure and processes underlying the 70% of the Earth that is under the oceans. I'm seeking graduate students interested in going to sea and working on a diverse range of problems. We will be studying how Eastern Lau spreading center magmatism is strongly influenced by volatiles expelled from the downgoing slab beneath the Tonga arc. The Aleutian megathrust experiment will study the coupling within the Alaskan megathrust.   http://www.ldeo.columbia.edu/~scw
