Juan R. Martinez - Morales Lab ( firstname.lastname@example.org ) is recruiting competitive postdoctoral researchers to participate in an interdiscipli nary project on c omparative tissue morphogenesis.
Research project/ Research Group description:
The main focus of our laboratory is to study cellular and molecular mechanisms involved in the morphogenesis of the vertebrate eye. Using the teleost models zebrafish and medaka, we investigate the machinery driving the folding of the retinal neuroepithelium.. Although it is generally accepted that optic cup formation follows a tissue - intrinsic program in vertebrates, several mechanisms have been postulated (bas al constriction, rim involution) and some important differences in cell behaviour have been reported among species.
Many important questions still remain open. Which is the relative contribution of each mechanism to the folding of the optic cup? Do they act in a cooperative manner? Do they have the same regulatory weight in different species? To answer these questions, we aim to integrate genetic information, imaging analysis of cell shape changes, and tensional forces distribution into coherent computation al models able to predict the key morphogenetic rules that shape the entire organ. We plan to extend our observations to mammalian tissue, by examining cell shape changes and tensions in 3D retinal organoids developed in vitro.
A key aspect of the project is to understand how classical signalling events, which have proved to be essential for the proper patterning of the organ, act in coordination with tensional forces. This highly interdisciplinary approach, combining genetics, imaging, biophysics and computational modelling should yield information relevant not only to understand optic cup formation, but also to deduce general self - organization principles of the living matter.

Job position description:
We offer a one - year renewable contract and full support to apply for external funding. Given the interdisciplinary character of the project above described, we are seeking talented and highly motivated postdoctoral researchers with a background either in Developmental Biology or in Biophysics. Previous experience with teleost models will be well received. The candidates should have good communication skills, critical for ensuring the success of the team effort.
