Her research is about supermassive black holes at the centers of massive galaxies. In particular, she investigates how these SMBHs influence the evolution of the galaxies they inhabit.
She has published more than 120 works in peer-reviewed journals, mostly on the study of the obscuring material around the nuclei of active galaxies, and on the triggering and feedback of this nuclear activity.
