Personal profile

Biography

I am a Principal Research Fellow at the International Centre for Radio Astronomy Research (ICRAR), The University Western Australia. Originally from Italy, where I did my undergraduate studies in Physics, I obtained my PhD in Astronomy in 2005 from Cornell University in the USA, where I worked on the topic of "Internal Kinematics of Disk Galaxies in the Local Universe" under the supervision of Prof Martha Haynes. Afterwards, I held postdoctoral positions at the Arecibo Observatory in Puerto Rico (USA) and Max Planck Institute for Astrophysics in Garching (Germany), and moved to Melbourne (Australia) in 2013, when I joined the Centre for Astrophysics and Supercomputing at the Swinburne University of Technology as an Australian Research Council (ARC) Future Fellow. I have been based at ICRAR, in Perth, since 2015, initially as ARC Future Fellow/Senior Research Fellow, and as Principal Research Fellow since 2020.

Roles and responsibilities

I lead the Local Universe research group at the International Centre for Radio Astronomy Research. Nationally, I am a Chief Investigator and Node Leader of the Australian Research Council Centre of Excellence for All Sky Astrophysics in 3D (ASTRO 3D), and a Councillor of the Astronomical Society of Australia. I also co-lead science and technical working groups for the WALLABY, LADUMA and HECTOR galaxy surveys.

Research

My main research interest is understanding the role of cold gas in galaxies and its connection with their properties and environment. I used the largest radio telescopes in the world to investigate how cold gas, which is ­ the raw fuel for star formation, ­ cycles in and out of galaxies.


My main contributions include leadership of the GALEX Arecibo SDSS Survey (GASS) and its extension (xGASS), which measured the atomic hydrogen properties of 1200 galaxies. Together with their molecular gas follow-up (xCOLD GASS), these surveys delivered the deepest observations of cold gas in the local Universe, uniquely probing the vastly unexplored gas-poor regime and yielding strong constraints to theoretical models and simulations of galaxy evolution. I also pioneered the application of spectral stacking to the study of gas scaling relations.

My current research focuses on the synergy between radio and optical integral-field spectroscopy observations, taking advantage of data from state-of-the-art surveys such as WALLABY on the Australian SKA Pathfinder (ASKAP) and the SAMI Galaxy Survey on the Anglo-Australian Telescope.
