Intérêts de recherche

I am an active participantin collaborative research projects addressing diverse inborn errors, includingdisorders of amino acid metabolism, organic acid metabolism, fatty acidoxidation and mitochondrial function. Some of these studies contribute tothe elucidation of etiology, pathogenesis and natural history, while othersfocus on improvement of diagnostic testing, management or treatment. Approaches include clinical studies of individual patients and families,population-based studies, and more fundamental research using modelsystems.
