The aim of this CIRM-SMF week is first to provide a basic and complete introduction to o-minimality and Hodge theory, and then to give a presentation of the recent applications of o-minimality to Hodge theory, for an audience of non-experts, with a special attention to junior researchers. Our hope is that this week will provide all technical tools, both in o-minimality and Hodge theory, to young researchers, and make possible to develop some new bridges between senior researchers in Model Theory and Hodge Theory.
