The position is related to the project "Computational models and methods to study the dynamics of gas hydrates". This project is a joint effort between the University of Stavanger and BCCS at the University of Bergen. Stavanger will employ a PhD student and supervise experimental work while the Post Doctor at BCCS shall apply computational simulation based on molecular dynamics to the study. It is expected that the Post Doctor contributes to the supervision of the PhD student in this area. The Post Doctor will further improve and adapt the molecular dynamics code Protomol, developed at BCCS, in order to carry out large scale simulations of gas hydrates. We expect enthusiasm and independence as well as ability to work in a team environment. The applicant should be well trained in numerical simulations and in the C++ programming language. He/she should have experience with UNIX/Linux based systems. Good knowledge of English is required. Applicants must hold a Norwegian doctorate in the relevant field or a foreign doctorate approved as being of equal status as the Norwegian doctorate. Other expertise equivalent to the Norwegian doctorate level may be considered. The expertise needs to be documented with scientific work of the same scope and quality as the said doctorate. Women, in particular, are invited to apply. If two applicants are found to be approximately equally qualified, the rules of gender-based quotation will be followed. Closing date: November 10th, 2006 Please send detailed CV, letter of motivation and contact information of two references to HR Coordinator Hilde Solvberg (Hilde.Solvberg@bccs.uib.no) with cc to Group Leader of Parallab, Professor Klaus Johannsen (klaus.johannsen@bccs.uib.no).
