I am a CNRS research engineer specializing in bioinformatics, scientific computing and the analysis of high-throughput biological data. I have a PhD and a dual background in biology and computer science. I currently lead the Bioinformatics & IT Service at IRCAN, where I support research teams in the design, processing, interpretation and reproducible analysis of complex biological datasets.

My work combines computational biology, next-generation and third-generation sequencing, microbiome analysis, genomics, transcriptomics, software development, Linux-based scientific infrastructure, and user-oriented support for research projects.

I am also interested in exploring genomes and biological sequences using in silico approaches, existing tools and custom developments to detect meaningful hidden patterns or cryptic information.

Nanopore sequencing and microbiome analysis

I am involved in projects using Oxford Nanopore long-read sequencing for microbiome and metagenomic analysis, including the comparison of full-length 16S rRNA sequencing and shotgun metagenomics for gut microbiome profiling. Current collaborations include projects with IRCAN, Dubai Hospital and the Scientific Centre of Monaco.

EpitopeMapper and k-mer sequence comparison

Development of k-mer-based approaches for identifying shared, unique or conserved peptide and protein sequence patterns across large proteomes. These tools aim to support exploratory analyses of immunogenicity, sequence similarity and motif detection.

Multi-omics and transcriptomics support

Support for RNA-seq, genomics, metagenomics and multi-omics data analysis for IRCAN research teams, including experimental design, workflow development, statistical analysis and biological interpretation.

Scientific computing infrastructure

Design, deployment and maintenance of Linux-based scientific computing environments, shared storage systems, backup strategies, internal web services and collaborative platforms for research data.

I have been involved in university teaching since 2006, mainly in bioinformatics, programming, genomics, metagenomics, microbiome analysis and scientific data processing.

Current teaching activities include:

• High-throughput sequencing and its applications to microbiome studies, Medicine, Université Côte d’Azur.
• Introduction to metagenomics, genome assembly and 16S rRNA barcoding, Master of Life and Health Sciences, Université Côte d’Azur.
• Introduction to Python, Master 1 Economic Expertise, Social Interactions and Economic Dynamics, Cognitive Sciences, Université Côte d’Azur.

Past teaching activities include biomedical engineering, medical dosimetry and radioprotection, C++ object-oriented programming, Python programming, medical files and DICOM format, bacterial genome assembly and primer design.

I regularly supervise or co-supervise (over 30 people) Master students, engineers, PhD students and postdoctoral researchers on topics related to bioinformatics, genomics, microbiome analysis, transcriptomics, scientific software and data infrastructure.

Main supervision topics include:

• Microbiome and metagenomic analysis, including breast cancer and gut microbiota projects.
