About me

I am an astrophysicist from CNRS working at the Institut de Planétologie et d’Astrophysique de Grenoble (IPAG) in France.

I succinctly present all my activities on the Loop research network. And encourage you to submit your papers to Frontiers journals, especially the Frontiers in Astronomy and Space Science, Milky Way and Galaxies for which I an Associate Editor.

Nearly all my publications are available open access and I maintain a special list of those related to astrocladistics on the present website.

Diversification of galaxies is my main research activity since September 2001. The goal is to depict the galaxy diversity that appeared during the history of the Universe, by using phylogenetic approaches borrowed from the evolutionary biology, in particular Maximum Parsimony (or cladistics). This incorporates domains like bioinformatics, statistics, mathematics, and the concepts of evolution as large. I have also applied this methodology on other astrophysical entities like stars or globular clusters.

    désolé de poster en français mais je ne suis pas suffisamment à mon aise en anglais.

    J’ai lu un article sur votre classification des galaxies dans le science et vie de juillet et j’applaudis votre découverte des deux mains. J’avais participé à un programme de classification des galaxies, galaxyzoo pour le citer, il y a quelques années et je me suis vite retrouvé confronté à des images sans aucun sens par rapport au systeme traditionnel, si vous me permettez de le décrire ainsi. Au contraire, j’ai trouvé votre classification particulièrement fine et juste pour venir jusqu’ici vous féliciter et vous encourager.
