Hi there! Welcome to my research website.

I am a faculty member of the chemistry department at the CNRS (French National Center for Scientific Research, http://www.cnrs.fr/en) and I work in the research unit EcoFoG (Ecology of French Guiana Forests, https://www.ecofog.gf/) located in French Guiana (France).

After graduating in organic chemistry I shifted my research program to interdisciplinary chemistry (short CV). I am deeply interested in organismal chemistry, which is the study of metabolites (small molecules) and enzymes produced by various organisms (plants, insects, fungi, microbes) at different phylogenetic scales. In particular I study how organismal bio-chemical diversity is correlated with phylogenetic and ecological factors in the context of convergent and divergent evolution. My favorite topics are: (1) insect-microbe symbiosis, (2) ecology and evolution of ants, and (3) plant-insect interactions.

One objective of my research is to study biosynthetic pathways in the context of evolutionary biology to understand the chemical and biochemical evolution of organisms. To achieve this goal it is necessary to combine different methods in:

  • analytical and structural chemistry (NMR 1D/2D, HR-MAS NMR, TOF-SIMS imaging, MS/MS molecular networking, metabolomics)

  • genomics (amplicon sequencing, metagenome mining, transcriptomics)

  • evolutionary biology (comparative phylogenetic methods)

Without them work will be boring.

Think, work, discover, publish, repeat.
