Postdoctoral opportunity: Thin-shell dynamics of subduction

Dear colleagues (with apologies for cross-posting),

We are pleased to announce a postdoctoral opportunity at the FAST laboratory
(University of Paris-Saclay) on `Thin-shell dynamics of subduction’. The successful
candidate will study the fluid mechanics of free (gravity-driven) subduction in
three-dimensional Cartesian and spherical geometry using a combination of
analytical (thin-shell theory) and numerical (boundary element and finite element)
approaches. The Cartesian results will be compared with laboratory experiments
performed at FAST. The project will also include analysis of the global catalog
of centroid moment tensors associated with deep earthquakes. A major goal of
the project will be to understand how spherical geometry influences the style of
deformation of subducted lithosphere and the state of stress within it.

The position is funded through the European Research Council Advanced Grant
SOFT-PLANET, and is for two years renewable for an additional year. The salary
will be commensurate with experience and includes full benefits. Candidates should
have expertise in some subset of the following: low Reynolds number hydrodynamics;
general geophysics; programming in Fortran and/or C++; the open-source
finite-element code ASPECT; boundary-element methods; and thin-shell theory.
Applicants should send a CV, a letter of motivation and the names of three references
to Anne Davaille ( and Neil Ribe
( The starting date is flexible anytime after
1 September 2023. The position will remain open until filled.

With best wishes,

Neil Ribe and Anne Davaille
