The Institute of Applied and Computational Mathematics (IACM) operating under the auspices of the Foundation of Research and Technology-Hellas (FORTH), has been awarded a Marie-Curie Development Host Fellowship. IACM is offering the opportunity to postdoctoral fellows from EU member and Associate States, with expertise in the fields of numerical methods for waves, geophysical wave propagation or geophysical flows, to carry out their research in collaboration with the researchers of IACM and the Departments of Mathematics and Applied Mathematics of the University of Crete. More specifically, IACM seeks to enhance its expertise in advanced computational methods for wave propagation problems with emphasis in geophysical wave propagation and geophysical flows, especially in exploration seismology and atmospheric flows. In order to make this task feasible, our expertise in linear waves (Schroedinger , Helmholtz and wave equations) and nonlinear waves (NLS, nonlinear elastodynamics, water waves and shock waves ), and our strong background in numerical analysis and computational techniques will assist fellows with background in geophysical wave propagation and geophysical fluid dynamics to strength their computational abilities, and built a solid background in Mathematical Geophysics, which is now becoming a prominent discipline of Applied Mathematics. The hosting site provides a stimulating research environment with excellent computational facilities and strong background in numerical computations, supervised by an enthusiastic group of experts in the field, who have intensive interaction with distinguished visitors and collaborators from all over the world. Selection of candidates will be based on a review of the submitted CV and supporting letters of recommendation. The duration of the fellowship is minimum 12 and up to 24 months. Financial support of 1700 euro (3100 including social security) for expenses and 400 euro for mobility per month plus expatriation cost 1200 euro is offered.
