Spondyloarthritis is a common chronic inflammatory rheumatic disease with a strong genetic component with over 50 susceptibility loci already identified. How these variants confer disease predisposition is however poorly understood. Convergent data suggest a role of regulatory variants in disease susceptibility.
The aim of my project is to identify regulatory variants associated with SpA susceptibility and to characterize the molecular mechanisms through which these variants modulate gene expression. A functional genomics approach will be used to achieve this goal. First, we will identify regulatory variants through eQTL mapping in cell types relevant for SpA pathogenesis then integrate the results with epigenetic marks to prioritize candidate variants to be characterized by functional assays.
As a rheumatologist, I have a longstanding interest in spondyloarthritis, a chronic disease which affects young people with a high impact on their quality of life. Since obtaining my MD, I have been practicing as an Assistant Professor in the Rheumatology Department of University Hospital Ambroise Paré in Paris. Concomitantly, I obtained a PhD in Genetics from Paris-Descartes University in 2013 and have integrated the "Infection and Inflammation" research unit at Versailles University. I recently joined the Julian Knight group at Wellcome Trust Centre for Human Genetics for a one year collaborative project investigating the role of regulatory variants in spondyloarthritis.
