Postdoctoral position. Centro Andaluz de Biología del Desarrollo (CABD), Seville.

Juan R. Martinez-Morales Lab ( is recruiting competitive

postdoctoral researchers to participate in an interdisciplinary project on comparative

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. Optic cup morphogenesis is an atypical model for epithelial

morphogenesis for, in contrast to well-known apical constrictions, it involves the folding

of the tissue towards its basal surface. Although it is generally accepted that optic cup

formation follows a tissue-intrinsic program in vertebrates, several mechanisms have

been postulated (basal 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 computational 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. We offer an adequate environment to mature

scientifically and eventually to become independent scientists. The CABD is

thematically focused on the topic of Cellular and Developmental Biology, and is well

equipped in terms of infrastructure, particularly for imaging analyses. Our research unit,

the department of Gene Regulation and Morphogenesis was recently awarded with the

María de Maeztu distinction of excellence. A series of external seminars by prominent

Spanish and international speakers are organized on a weekly basis. In addition, a

biweekly series of seminars allow PhD students and postdoctorals to present their

work. English is the official language in the CABD as well as in our internal seminars,

as international researchers are frequent visitors/members in our group.
