Research Interest:
My laboratory studies the mechanisms of pathogenesis of neuromuscular disorders with a primary focus on Duchenne Muscular dystrophy (DMD). In addition we are developing pertinent therapeutic strategy using translational research, an emerging field which can be summarized as understanding the cause of a disease and learning from it in order to develop innovative therapeutic strategies.

Our long-term projects focus on RNA and DNA editing and gene transfer as therapies for neuromuscular disorders, but they will also include more fundamental research on muscle function. In particular, our lab uses the newest technologies, such as virus-mediated exon-skipping and the CRISPR/Cas9 genome editing tool.

Our primary work is focused on developing a therapeutic strategy for patients suffering from severe muscular dystrophy DMD caused by mutations in the first part of the gene. Our preliminary results indicate that this region can be removed from the messenger RNA without losing the protein function (or with minor reduction in the functionality of the protein). Therefore, forcing the expression of this new smaller protein isoform is a promising therapeutic strategy for patients with mutations in that region. Moreover, determining the exact role of this protein domain will improve our general understanding of muscle physiology and might help find therapeutic strategies for other disorders in the long term.
