The MARUM Excellence Research Cluster (The Ocean in the Earth system) at the University of Bremen, Germany, will be filling:

Specifically, we are searching for enthusiastic and dynamic young researchers with a strong background in the fields of "Geotechnology/rock deformation" and "Numerical modeling of granular materials".

One candidate will develop his/her research program in the framework of marine geotechnical research groups in one of the following projects:

• Design and construction of a high-stress shear apparatus / Tests on sediment and rock samples at pressure-temperature conditions similar to the seismogenic zone / Earthquake mechanics
• Dynamic triaxial tests on sediment liquefaction / Numerical modeling of pore pressure development under quasi-static as well as cyclic stresses.
• Development and construction of seagoing pore pressure instruments and borehole technology"

Experience in research applications and operation of soil mechanical testing equipment is desirable. Applicants with interdisciplinary approaches in their research are encouraged to consult our websites (http://www.marum.de/Marine_Geotechnik.html) for potential synergies and cooperation with other groups. The individual should hold a PhD in Geology, Civil Engineering, or a related discipline and have some postdoctoral experience. Please address enquiries to Prof. Dr. A. Kopf (akopf@uni-bremen.de).

Another candidate will work in the field of sediment physics and mechanics on both micro-scaled and large-scaled levels utilizing numerical granular-based simulation techniques. Her/his research work will focus on one of the following aspects:

• Mechanics of granular materials / Deformation and failure of geological materials
• Characterization of sediment-physical processes during destabilization / Stability of slopes / Prediction of landslide initiation mechanisms
• Fault initiation and evolution / Fracturing of geomaterials / Rupture propagation
• Quantification of pore pressure evolution in porous media combining granular simulation methods with continuums models.

Please consult our websites for more details on research projects, potential synergies and cooperation with other groups (http://www.marum.de/AG_Sedmod.html). The successful applicant should have a demonstrated record in numerical modelling techniques (e.g. particularly PFC) and ideally a strong background in sediment physics, rock mechanics, geodynamics, structural geology or related research areas. The candidate should hold a PhD in Geophysics, Physics, Geology, Civil Engineering, or related disciplines. Please address enquiries to Prof. Dr. K. Huhn (khuhn@marum.de).

The positions are first limited to a term of up to 4 years and funded by the German Science Foundation (DFG). Salary and benefits are commensurate with the federal German employee scale TVL13. Applications should include a CV, a list of publications, a statement describing research interests, the applicant's research and technical background as they relate to the position, and contact information for 3 referees.

We will begin reviewing applications two weeks after publication of this announcement. Applications should be directed electronically to Mrs. Petra Renken (prenken@uni-bremen.de) or by mail to:
