PhD and Postdoctoral positions in seismology
The Dublin Institute for Advanced Study invites applications for a 4-year Ph.D. and a 1-year Postdoctoral positions in seismology. The positions are in the seismology group at DIAS, which has a broad, highly regarded research programme in regional and global seismic imaging, waveform and array tomography and lithospheric dynamics.
The recent growth in the number of broadband seismic stations around the world makes it possible to image the Earth's interior in unprecedented detail. This presents opportunities for exciting new discoveries, relating to long-standing problems of basic Earth science. In these PhD and Postdoctoral research projects, the lithosphere and underlying mantle will be imaged using very large datasets of surface-wave measurements, including the fundamental and higher modes. The data will be related to Earth structure using probabilistic seismic inversions and computational-petrology inversions, targeting fundamental problems of plate tectonics and lithospheric dynamics.
Duration: 4 years.
New methods for automated surface-wave measurements can produce large sets of very accurate, very broadband phase-velocity data. In this project, the methods will be fine-tuned and applied to Asia and surroundings, as well as other regions. The range of problems that may be addressed includes the mechanisms of continental convergence and mountain building (Tibet, Pamir and elsewhere), origins of enigmatic intraplate volcanism (western Mongolia and elsewhere), dynamics of the lithosphere and its interactions with the convecting mantle beneath it.
Students at DIAS receive broad training in geophysics. While focussing primarily on their research, they also attend many short courses, workshops, 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/very good 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).
Duration: 1 year
Understanding the evolution and dynamics of the lithospheric plates requires knowledge of their structure, temperature and thickness. The signal of these properties in seismic data is subtle. Current tomography models map the large-scale seismic velocity structure of the plates but the model non-uniqueness still limits the inferences on the lithospheric structure that can be made. This project will capitalize on the resolving power of our group's massive, recently assembled global datasets (fundamental and higher mode Rayleigh and Love waves) and on our recently developed seismic and petrological inversion methods. The focus will be on the application of the methods, targeting new insights into the mechanisms of the lithospheric dynamics and evolution, at scales from global to regional.
Qualifications: a PhD in geophysics or related field is required. Substantial computing and programming experience and a good command of English are essential. A publication record commensurate with career stage is expected. Experience in the seismic imaging of the lithosphere 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.
