Marie Delattre

I would like to understand the evolutionary dynamics of cellular processes. I established my lab in 2009. Currently, I would like to understand to what extent cellular mechanisms evolve without altering the basic function they sustain. I am also very impressed by the fact the small cellular changes can precondition the emergence of new  reproductive modes.  I have always been using nematodes as model system. I believe these worms are ideal to address cell biological, developmental and evolutionary questions.

Caroline LAUNAY, Research assistant, Engineer CNRS IE1

Caroline Launay

I am a lab manager and have a diploma from the ESBS School of Strasbourg. I first worked on tRNA biochemistry in Saclay. I joined the lab in 2012. Currently, I am working on the diversity of species within the Mesorhabditis genus. I have identified 11 auto-pseudogamous species and 2 sexual species. I am also exploring how the choice between amphimictic and gynogenetic development is decided in the eggs of M. belari.

Manon GROSMAIRE, PhD student

I started my PhD with a fellowship from the French Ministry of Research in 2015. I have been trained as a biologist in the University of Lyon (UCBL). I am stuying the pseudogamous mode of reproduction in Mesorhabditis species. I have also been able to establish the CRISPR/Cas9 technique of genome engineering in several Caenorhabditis species.

Joris DIENG, Master student M2

I work on hybrid incompatibility between Mesorhabditis species.

Jia Qi CHENG-ZHANG, Etudiant Erasmus

I work on spermatogenesis in males of the M. belari species. I want to understand why sperm cells that carry the Y chromosome are much more efficient than X-bearing sperm to fertilize oocytes.
