Présentation
I am a research scientist specializing in yeast genomics and bioinformatics, with a focus on the comparative genomics of yeasts associated with food processes. My expertise lies in bioinformatics and computational biology, particularly in sequence analysis of industrial yeast genomes and in comparative genomics of yeasts from both technological and natural habitats.
In 2025, I was the first author of a comparative genomics study of the yeast Monosporozyma unispora (FEMS Yeast Research, DOI: 10.1093/femsyr/foaf016). This research highlighting their genetic diversity, adaptive traits, and relevance for both evolutionary studies and emerging biotechnological applications.
In 2024, I was the first author of a study on the genomic, genetic and phenotypic landscape of Candida anglica yeast population isolated from french PDO cheeses (Food Microbiology, DOI: 10.1016/j.fm.2024.104584). This work investigated how domestication and adaptation to this specific environment have shaped their genomic signatures, thereby informing our understanding of evolutionary processes.
In 2023, I was the first author of a comparative study of the oleagenous yeast Yarrowia lipolytica (Journal of Fungi, 9:76; DOI: 10.3390/jof9010076). With my colleagues I investigated 56 natural isolates and demonstrated that this species exhibits low genetic diversity, with a pan-genome closely resembling the core genome, suggesting a relatively recent evolutionary trajectory. Despite this, we observed substantial phenotypic diversity among strains, particularly regarding lipid metabolism.
In 2021, I was the first author of a study on the domestication of bakery yeast (Current Biology, 31:1–12; DOI: 10.1016/j.cub.2020.11.016). This work focused on Saccharomyces cerevisiae strains used in bread-making and revealed that domestication has been accompanied by dispersion, hybridization, and divergent selection processes, shaped differently by industrial and artisanal practices.
Earlier, in 2009, I co-authored the genome sequence analysis of the first wine yeast strain Saccharomyces cerevisiae EC1118 (PNAS, 106:16333–16338; DOI: 10.1073/pnas.0904673106), which uncovered unprecedented eukaryote-to-eukaryote horizontal gene transfer events. This study shed light on the genomic innovations that have contributed to the adaptation of S. cerevisiae wine strains to fermentation environments.
Collectively, my research integrates genomic sequencing, bioinformatics, and comparative evolutionary analyses to better understand yeast diversity, adaptation, and domestication, with direct implications for biotechnology and food fermentation processes.
