My research interests have been ranging from the investigation of the
cosmic microwave background to the study of gravitational wave sources
and star formation in the early universe.
In the last few years I have been increasingly involved in the study
of the first stars, which now represent my principal field of work.
Specifically, I am interested in the contribution of the first stars
to cosmic reionization and metal enrichment. Both of these processes
lie at the forefront of research in cosmology and represent core
science topics of many ground and space-based observing facilities
under construction. More recently, I have started to work on the
evolution of cosmic dust, with particular interest in sources of dust
at high redshift.
My research activity is mainly theoretical, but closely linked to the
interpretation of experimental data.
I actively collaborate with members of Italian, European, US and Japanese
institutions, among whom Andrea Ferrara (SNS), Ruben Salvaterra
(INFN, Brera), Benedetta Ciardi (MPA, Munich),
Evan Scannapieco (Arizona University), Kazuyuki Omukai (NAO, Tokyo).
