Dear Colleagues,
The Dublin Institute for Advanced Studies invites applications for a
Post-Doctoral Position in Seismology and Petrological Modelling.
Duration: 1 year initially, with a (strong) possibility of extension,
subject to funding confirmation.
Salary: €36,489 - €43,394 in the first year, depending on experience
and qualifications, with annual increment(s) thereafter.
Start date: as soon as possible.
The successful candidate will join the active, growing research group at
DIAS working on the seismic imaging and petrological modelling of the
lithosphere and underlying mantle. We do global and regional tomography
using the fundamental and higher modes of the Rayleigh and Love waves
and invert the data for seismic-velocity structure and anisotropy.
We address the inverse-problem non-uniqueness by means of Bayesian
(MCMC) inversions. We model and invert seismic and other data using
methods of computational petrology, in collaboration with Dr Javier
Fullea
and his group at DIAS.
This project will capitalize on the high imaging resolution yielded by
our
massive global datasets and on our recently developed seismic and
petrological inversion methods. The focus will be on the application of
the
methods (with tuning and further development, as appropriate), 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. Substantial research experience and proven publication
record
are preferred, but recent PhDs with strong relevant expertise will also
be
considered. 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 (sergei<at>cp.dias.ie), 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 projects please contact Dr. Sergei Lebedev
(sergei<at>cp.dias.ie). DIAS is an equal opportunity employer.
We would appreciate your passing this on to anybody potentially
interested
in this opportunity.
Many thanks,

Sergei Lebedev2017-11-27 07:54:55Dear Colleagues,
The Dublin Institute for Advanced Studies 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 to 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.
Ph.D. Studentship
-----------------
Duration: 4 years
Stipend: €18,000 per year, tax free.
Start date: 1 March, 2018, or as soon as possible after that.
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.
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 (sergei<at>cp.dias.ie), 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
(sergei<at>cp.dias.ie).
Post-Doctoral position
----------------------
Position: Post-Doctoral Researcher in Seismology, Dublin Institute for
Advanced Studies
Duration: 3 years
Salary: €36,489 - €43,394 in the first year, depending on experience
and qualifications, with annual increments thereafter
Start date: 1 March, 2018, or as soon as possible after that.
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 group's
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 sharper images of the deep upper mantle. For this,
improved, 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
