My main area of research is Algebraic Geometry, with emphasis in Hodge Theory and algebraic cycles. I am interested in developing techniques to compute periods of Hodge cycles explicitly, and use this information to study algebraic varieties. I am particularly interested in the Hodge conjecture, and its variational version. My work have concentrated in the case of hypersurfaces, where we can associate to every non-trivial primitive Hodge cycle an Artinian Gorenstein algebra. Lately this relation has specially dragged my attention.
