The Computational Geosciences group at the University of Cologne  
invites applications for a Research Assistant / PhD position in:

Discrete-Element-Simulations of wind-blown sand and dust emission,

starting as soon as possible.

The position is offered within the research project “Particle-based  
simulation of dust emission”, funded by the German Research  
Foundation, and is initially for 3 years with a weekly working time of  
29.87 hours (75% position). The salary is based on the German TV-L E13  
scale if terms and conditions under collective bargaining law are  

Job description: The candidate will develop a numerical tool, based on  
the Discrete-Element-Method (DEM), to simulate the transport of  
wind-blown sand particles along the surface and the concatenated  
emission of dust particles. To this end, an existing DEM open-source  
software for massive parallel DEM simulations of granular systems  
(LIGGGHTS/LAMMPS) shall be extended to incorporate a stochastic model  
for inter-particle cohesive forces as well as a description of  
hydrodynamics to model particle-fluid interactions. The candidate will  
collaborate closely with the Atmospheric Modeling group of the  
Institute of Geophysics and Meteorology, as well as with the Granular  
Matter group of the Physics Department and the DLR / Cologne.  
Moreover, the candidate will have the opportunity to actively  
participate in wind-tunnel or field experiments to validate the  
numerical simulations.

Requirements: We expect strong interest in computational and physical  
modeling of granular systems and particle transport in turbulent  
surface flows. Applicants should have a Master-of-Science-equivalent  
university  degree in physics, mathematics, computer  sciences,  
geophysics or meteorology, and strong background in programming with  
C++ and MPI. Experience with DEM simulations, and in particular with  
LIGGGHTS/LAMMPS,  is of great advantage. Candidates must have  
excellent  communication skills both in written and spoken English.

The University of Cologne is an equal opportunity, affirmative action  
and diversity supporting employer.  Handicapped persons will be given  
preference to other equally qualified applicants. Applications from  
women are particularly welcome and will be preferred in case of equal  
qualification and capacity.

Interested candidates should send a CV; a cover letter describing  
background, training and research interests; certificates; and the  
contact information of two referees as a single PDF to  
eric.parteli at uni-koeln.de. Please clearly indicate which position you  
apply for.
Review of applications will begin after April 30th, 2017 and continue  
until the position is filled.
