Benedetta Ciardi

Max Planck Institute for Astrophysics

Benedetta Ciardi is a researcher at the Max Planck Institute for Astrophysics (MPA, Garching, Germany). Since her PhD thesis, conducted at the University of Florence under the supervision of Prof. Andrea Ferrara, her interests have focused on investigations of cosmic reionization. Following a PreDoctoral fellowship at the Center for Astrophysics (Cambridge, USA) and a Marie Curie PostDoctoral fellowship, she has become a staff member of MPA, where she has continued her theoretical studies of the high redshift universe and has become involved in a number of observational endeavours aimed at constraining the infancy of our universe. As the 21cm line emitted by the atoms of neutral hydrogen during the various stages of reionization is considered the most promising tool to investigate this process, several radio telescopes have been built and are being planned with the aim of detecting such line. Among them LOFAR is located in Europe, with one antenna field hosted by MPA and managed by Benedetta. Her academic achievements have been recognized with a Marie Curie Excellence Award and a Knighthood of the Order of Merit of the Italian Republic.
