The role
We are seeking a highly motivated candidate, strongly interested in interdisciplinary science, to join our group as a Ph.D. student or a Postdoc and work on a project at the crossroads between Computer Science and Developmental Biology.

The project aims at developing computational methods and models to better understand how robustness to biological noise is achieved during the development of Drosophila embryos. This will be done by first quantifying and characterising Drosophila embryogenesis variability at the single cell scale.

The successful candidate will be tasked to build statistical representations of the morphogenesis of Drosophila embryos at the single cell scale by combining image analysis, big-data science and data visualisation. To this end, the candidate will first develop novel image and big-data analysis algorithms. These algorithms will be first applied to 3D movies of Drosophila embryos acquired with state-of-the-art light-sheet fluorescence microscopes. The successful candidate will then develop novel algorithms to combine the set of recorded embryos together to build a single-cell scale, in-toto, atlas of Drosophila embryogenesis.

Depending on the advancement of the project and the candidate preferences, the second part of the project will then focus around either integrating complementary single-cell omic data to the atlas or developing machine-learning based methods to analyse, detect and classify cell patterns in the developing embryo.

About the team
We are a group of computer scientists with a strong interest in biology in general and more specifically in embryonic development. We develop novel computational methods and models that allow the analysis of very large 3D movies of animal embryonic development (up to 2TB per movie). We work closely with biologists to tailor our methods so that they help to address fundamental biological questions.

The developmental biology question that mainly animates us is to better understand the mechanisms driving the reproducibility of embryogenesis.

The Institute
The Turing Centre for Living Systems (CENTURI) is an interdisciplinary project located in Marseille (France).
CENTURI aims at developing an integrated interdisciplinary community, to decipher the complexity of biological systems through the understanding of how biological function emerges from the organization and dynamics of living systems.

The project federates 15 teaching and research institutes in biology, physics, mathematics, computer science, engineering and focuses on Research, Education and Engineering, 3 missions that hold interdisciplinary as their core principle.

The research and training programmes implemented under the auspices of CENTURI will foster new collaborations, transform practices, attract new talents and thereby contribute to making the Luminy campus a leading site for the ‚Äč‚Äčinterdisciplinary study of biological systems.
