Amir Khan
Institution: ETH Zürich
Open Until: 2017-10-31
The aim of this project is to investigate and characterize the nature of Earth’s mantle transition zone and the seismic discontinuities that bound it. While the transition zone is known to be bounded by the major seismic discontinuities (“410” and “660”), there are many fundamental questions that remain to be addressed. Among others, can the observed variations in transition topography be explained in terms of thermal perturbations only or are compositional variations equally important? Does the 660-km discontinuity reflect a change of phase in an isochemical mantle or is a chemical change also required?
The successful candidate is expected to map the structure of the transition zone and upper mantle on both regional and global scale using multiple seismic observations of P-to-S conversions (receiver functions), reflections (SS and PP precursors), triplications, and surface-wave dispersion data. The project includes interpretation of the results with the aim of improving our understanding of the dynamics and evolution of Earth’s mantle through the consideration of mineral physics-based approaches.
We are looking for persons who hold a MSc in Geophysics or Physics, have a strong background and interest in seismology and mathematical (geo)physics. We expect the candidate to have experience in programming (e.g., Fortran, Python) and be proficient in written and spoken English.
The Department of Earth Sciences at ETH Zurich offers excellent working conditions in a highly stimulating environment. The salary will be in accordance with the regulations of ETH Zurich.
We look forward to receiving your online application including a CV, statement of research interests, complete course grades and transcripts, and the names and addresses of two references. The selection process starts now (September 2017) and will continue until the position is filled.
Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered. Should you run into difficulties when submitting your application please send an email to recruitingsupport<at>ethz.ch for advice.
