Research Focus

I lead the Maelstrom Research Platform ( which provides the international research community from diverse disciplines with resources (expertise, methods, and software) to leverage and support data harmonization and integration across studies. The Maelstrom team develops methods and software; conducts methodological research; generates catalogues of study metadata; and creates infrastructures supporting data management, harmonization and co-analysis.
