The "R" Lab is a pluri-disciplinary laboratory combining Integrative Biology approaches, Evolutionary Cell Biology and Innovations. We use physics, chemistry, engineering, molecular and cellular techniques to study the secretory pathway. We combine an evolutionary approach from Planctomycetes (Devos & Reynaud, 2010) to Human tissue via Protists and new biophysical and optical methods ranging from cell "morphing" (Tängemo et al., 2011) to Light Sheet Microscopy for 3D imaging (Reynaud et al., 2008).

Our ultimate goal is to achieve a continuum of knowledge from single bacteria excretion capacity to complex tissue secretion ability in an organism context. We have successfully used bioinformatics and cell biology to define compartmentation related protein families (Lsg1) and stream line evolution of the secretory pathway. We intend to further develop our approach by closing the knowledge gap between bacterial secretion and higher eukaryote excretion: the Protists. We have provided our expertise during Tara Oceans as the Imaging Coordinator and now we benefit from a possibility to access large datasets of genomic and imaging data of marine protists.

We also provide advices and optical set-ups to research groups and collaborate extensively with the private sectors (Carl Zeiss MicroImaging GmbH, Aquamarine Power Ltd, Tech Works Ltd).

The scientific activities of the Tara Oceans expedition, led by EMBL senior scientist Eric Karsenti, present an unprecedented effort that resulted in 35,000 samples containing millions of small organism collected in more than 210 ocean stations, chosen for their climatic significance or biodiversity.
