Advancing our understanding of neuromuscular diseases through stem cell biology,
disease modelling and regenerative medicine.
My current research focuses on modeling neuromuscular diseases (NMDs), such as SMA, DMD, DM, FSHD, and Lama2-CMD, using patients' induced pluripotent stem cells (hiPSC) to enhance our understanding of the genetic and cellular mechanisms behind these debilitating skeletal muscle disorders.
A key project, funded by the European Commission through a MSCA Reintegration fellowship, aims to identify novel disease-causing genes in patients facing diagnostic deadlocks and to explore the mechanisms behind previously undiagnosed Muscular Dystrophies (UMDs) to guide their diagnosis and classification, potentially leading to new therapies.
We collaborate closely with hospital services and have compiled extensive collections of biological samples for experimental use. By integrating advanced and functional technologies, such as transcriptomics, multi-omics,GS, calcium imaging, and MEA, we can pinpoint affected genes, biological pathways, and functional properties in undiagnosedromuscular diseases, paving the way for innovative therapeutic strategies.
Additionally, we are investigating the pathomechanisms of Laminin a2 deficiency related muscular dystrophy (LAMA2-RD), a common congenital muscular dystrophy with no existing cure. Overall,PSC-based models provide unique opportunities to explore various aspects of genetic NMDs, identify new genes, validate pathogenic variants, and define the early stages of muscle wasting, while also supporting the development of personalized treatment options for these conditions.
LAMA2-RD CONFERENCE
ISTANBUL 2026
I was so delighted to present my work at the LAMA2 Istanbul 2026 Conference and to share it with the LAMA2 community.
Thank you to the organisers:

Congratulations to Imane BEN-DAOUD
for winning the Best Oral Presentation award at the MarMaRa Annual Scientific Symposium that took place in Luminy !
Imane presented her PhD work on modeling muscular dystrophy caused by a new PLEC1 mutation using patient’s hiPSC, and made me a proud and very happy PhD supervisor!
A big thank you to Institut Marseille Maladies Rares (MarMaRa) and team for organising a great event, and congratulations to the winners of the Best Poster Presentation awards!







I was very proud and happy to have presented my research at Sorbonne University for the LAMA2 foundation.

New funding
October 2025

New funding from the French Foundation for Rare Diseases to advance
diagnosis of muscular dystrophies.
I am delighted to share that our group at Marseille Medical Genetics (Inserm / Aix-Marseille University) has received funding from the French Foundation for Rare Diseases as part of its 2025 specific call for projects.
This funding will support an innovative multi-omic study aimed at improving the diagnosis of patients affected by muscular dystrophies but who remain without a definitive genetic diagnosis. Despite advances in sequencing technologies, many patients still lack a clear molecular diagnosis, limiting clinical management and therapeutic perspectives. Our approach
combines genomic, transcriptomic, and proteomic analyses to better understand disease mechanisms and identify new diagnostic markers.
The project started in September 2025 and is part of the broader mission of our laboratory to bridge fundamental research and precision medicine in rare diseases.
I would like to warmly thank the French Foundation for Rare Diseases for their support, as well as all collaborators and patients involved in this collective effort.
