Ph.D. position to study organogenesis in Drosophila melanogaster. Cellular migration and pathfinding are two processes essential for morphogenesis. Their precise temporal and spatial coordination is crucial for cells to be able to establish connections over long distances. Correct control allows development of multicelular organisms. Defects in control are associated with cancer development. Our group is interested in the molecular mechanisms of cell migration, cell elongation and pathfinding using Drosophila's tracheal and nervous systems as models. This Ph.D. project involves the study of cellular and molecular mechanisms involved in organogenesis of both nervous and tracheal systems, using a collection of mutants selected due to their specific tracheal and nervous system phenotypes. Interested candidates please send CV and motivation letter to: Sofia J. Araújo Email: sofia.araujo@irbbarcelona.org Deadline for applications: 31st December 2009. IRB Barcelona (IBMB-CSIC) aims to promote multidisciplinary research of excellence at the interface between biology, chemistry and medicine, to foster collaborations with local organisations and international research institutes, and to provide high-level training in the biomedical sciences to staff, students and visitors. IRB Barcelona is located in the Barcelona Science Park, a centre in which first-class public research converges with the private sector in a stimulating, vanguard scientific environment.
