PhD and Postdoc Positions in Seismology
Dublin Institute for Advanced Study invites applications for one Ph.D. and one Postdoctoral position in seismology. The positions are in the seismology group at DIAS that has an active research programme in regional and global seismic imaging, waveform and array tomography and lithospheric dynamics. The positions are part of a large new project that will deploy broadband, ocean-bottom seismometers in the North Atlantic, across the vast Irish offshore, giving the successful candidates opportunities to participate in the deployment and retrieval cruises.
The two research projects are on waveform tomography, at the North Atlantic and global scales. Advances in the tomography methods will be implemented and, together with the unique new data, should enable imaging the N Atlantic with unprecedented resolution. Scientific targets of the research include the evolution of the lithosphere of the N Atlantic and its margins, the origins of the enigmatic N Atlantic Igneous Province volcanism, the deep structure of the Iceland Hotspot and its effect on the evolution of the region.
Duration: 4 years
The new data created in this project, used together will all other available broadband data, will improve the resolution of tomographic imaging in the entire N Atlantic. In this PhD project, new, state-of-the-art models of the crust, now available for the N Atlantic and adjacent regions, will be incorporated into waveform tomography as prior information (background models). Errors in earthquake source parameters (locations, source mechanisms) can limit the resolution of the imaging; they will be dealt with by means of iterative inversions for Earth structure and the source parameters. The applications of the improved imaging methods will target discoveries on the lithospheric structure and evolution and on the hotspot-lithosphere interactions, in the N Atlantic region and beyond.
Students at DIAS receive broad training in geophysics through short courses, workshops, and attendance at international schools and major conferences. PhD students in the seismology group have been very successful in their research, publishing actively and winning international and national awards for their work.
Applicants should have excellent grades, preferably an advanced degree (M.Sc. or equivalent), background in geophysics, physics or mathematics and strong computing skills, including programming. To apply, please e-mail a complete academic CV, a statement of research interests, English proficiency certification if applicable (DIAS requirements are the same as those at UCD: http://www.ucd.ie/international/study-at-ucd-global/ucdenglishlanguagerequirements/), academic transcripts, and the names and contact details of 3 academic referees to Dr. Sergei Lebedev (firstname.lastname@example.org), with "seismology Ph.D. position" in the subject line. Consideration of applications will begin immediately and continue until the position is filled. For additional information on the project or on studying at DIAS please contact Sergei Lebedev (email@example.com).
Position: Post-Doctoral Researcher in Seismology, Dublin Institute for Advanced Studies
Waveform tomography with 3D waveform sensitivity kernels and massive datasets.
Understanding the Cenozoic evolution of the N Atlantic requires understanding the Iceland Hotspot's effects on the dynamics, uplift and volcanism of the margins and the hotspot-ridge-lithosphere interactions. Our current waveform tomography with large datasets performs well in imaging the lithosphere, and the new data will improve the lithospheric imaging in the entire N Atlantic. To understand how the hotspot affects the lithosphere, we also need improved images in the deep upper mantle. For this, accurate, 3D sensitivity kernels for regional S and multiple S waves are needed. In collaboration with Dr Tarje Nissen-Meyer and his group at Univ. Oxford, the successful candidate will implement the computation of the 3D kernels for body and surface waves and apply the improved tomography methods to the latest N Atlantic and global datasets.
Qualifications: a PhD in geophysics or related field is required. Substantial computing and programming experience and a good command of English are essential. Substantial research experience and proven publication record are preferred, but recent PhDs with strong relevant expertise will be given full consideration. Experience in the seismic imaging of the lithosphere or computational seismology is desirable.
To apply: e-mail a complete academic CV, including a list of publications, a statement of research interests, and the names and contact details of 3 academic referees to Dr. Sergei Lebedev (firstname.lastname@example.org), with "Postdoctoral position" in the subject line. Consideration of applications will begin immediately and continue until the position is filled. For additional information on the project, please contact Dr. Sergei Lebedev (email@example.com).
