Myositis is a heterogeneous group of complex muscle diseases in which inflammatory changes of skeletal muscles lead to muscle weakness. Other organs can be involved in myositis, including the skin, lungs, heart and joints.

A new approach based on the presence of clinical manifestations, serum autoantibodies and pathological changes in muscle biopsies has led to major advances in characterization and treatment decision-making in myositis.

My research program aims to characterize scleromyositis, a distinct form of myositis associated with features of scleroderma, another connective tissue disease, using a clinico-sero-pathological approach.

My research projects use clinical and biological data from the Centre hospitalier de l'Université de Montréal myositis cohort and a pan-Canadian multicenter myositis registry (Canadian Inflammatory Myopathy Study). I also collaborate closely with other national and international research teams in rheumatology, neuropathology and immunology.
