(from Andre Giesecke, HZDR, Germany )

The Institute of Fluid Dynamics at Helmholtz-Zentrum Dresden-Rossendorf (HZDR, https://www.hzdr.de) invites for applications for a PhD position in the field of experimental fluid dynamics.

The research tasks involve experiments on precessing fluid flows and are essential for the preparation of the large scale dynamo currently under construction at HZDR.

The PhD student will be responsible for running regular experiments at the water precession experiment and will conduct he related measurements. The tasks include an upgrade of the experiment and the involvement in the preparation of the forthcoming dynamo experiments. Intensive cooperation is mandatory with the project partners at Ruhr-Universitaet Bochum (Prof. R. Grauer), where related numerical models are conducted.

The position will be available from 1 July 2019. The employment contract is limited to three years.

REQUIREMENTS:

• Diploma or M.Sc in physics/mechanical engineering or related subjects with very good marks and a profound background in fluid dynamics and/or magnetohydrodynamics
• experience in the operation of experiments, preferably in the field of fluid dynamics
• willingness for close cooperation with project partners from Universitaet Bochum who will conduct related numerical studies (includes travel to Bochum 1-2 times a year)
• scientific approach to research questions, self-dependent working style and excellent written and oral communication skills in English

WE OFFER:

• high scientific professional networking as well as scientific excellence
• internationality and diversity
• interesting and diverse tasks, flexible working hours, salary based on the collective agreement TVöD-Bund
• equality of opportunity and family-friendly structures, corporate health management
• attractive work and research terms in a highly motivated team

Kindly submit your completed application (including cover letter, CV, diplomas/transcripts, etc.) by 30 April 2019 online via https://www.hzdr.de/db/Cms?pNid=490&pOid=57754&pContLang=en

from Andy Jackson (ETH Zürich, Institut für Geophysik)

The Earth and Planetary Magnetism Group at the Institute of Geophysics at ETH Zurich studies planetary magnetism with a strong focus on the Earth. Part of our group is devoted to the mechanisms underlying the generation and evolution of the magnetic field of a planet following theoretical, numerical and experimental approaches.

Postdoctoral Research Fellow in Magnetohydrodynamics (100%)

The position will develop theory and algorithms for the solution of a new class of self-consistent solution to the governing equations of dynamo theory. Depending on background and experience, the fellow will work on one of the following topics: (i) Application of optimal control to the inviscid fluid dynamical equations, together with analytic treatment of viscous effects (ii) Implicit methods of time-stepping (iii) Development of algorithms for anelastic treatment of giant planets. (iv) Understanding geomagnetic reversals. The project is funded by the ERC and the position is for 2 years in the first instance, with the possibility of renewal.

The successful candidate will have a background in mathematics or physical sciences and be expected to (i) carry out his/her own research projects, (ii) co-supervise undergraduate- and graduate-level thesis projects, and (iii) possibly contribute to the teaching of general geophysics courses. We seek a good team-player who can join a small team of about 10 others. Evidence of high performance computing experience is required. The working language of the department is English. At the time of the appointment, the successful candidate must have a doctoral degree in geophysics or a related subject.

We look forward to receiving your online application including the following documents: a full CV, short statement of experience and research interests. Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.
