I am interested in Cosmology since there are many many open questions which people are trying to understand and interpret. We are now in the era of precision cosmology so it's going to be very exciting. My area of research is mostly based on the study of the polarization of the Cosmic Microwave Background (CMB).
I have recently started a tenure track at University of Catania, (which is also my home town!), where I joined the Astrophysics group in the Observatory and started teaching (both grad and undergrad students). Before that I worked as a staff researcher at University of Rome - Tor Vergata where I joined the cosmology group led by Nicola Vittorio and Marina Migliaccio. I spent ~5 years in my beloved California where I had the great opportunity of being a PostDoc at UC Berkeley and at the Center for Computational Cosmology, (led by Julian Borrill) and at KIPAC (Stanford University, CMB group led by Chao-Lin Kuo). Thanks to this experience, I got actively involved in several CMB experiments to date: Simons Observatory, CMB-S4 and LiteBIRD.
Currently, I have several responsability roles: SO pipeline leader of Galactic and Extra-galactic science, and Simulation Production Manager for LiteBIRD. I am currently working on systematics assessments for Litebird and SO due to gain drifts and beam systematics on one hand. On the other hand, I am interested in improving the foreground modelling by identifying area of homogeneity in the spectral quantities we use to parameterize the Foreoground emission.
I graduated in Astrophysics at the International School of Advanced Studies (SISSA) in Trieste (Italy) on October, 2017 and I worked on data analysis for Cosmic Microwave Background ground based experiments under the supervision of Carlo Baccigalupi and Giulio Fabbian since October 2013 (when my PhD started)..
On December, 2016 I got a Master in High Performance Computing (MHPC) meant to improve the young scientists capability in writing massively parallel codes, installing and handling any scientific library, object oriented programming, finite element methods, iterative methods, large-data manipulation, parallel linear algebra and advanced numerical analysis.
Challenges for the forthcoming CMB polarization experiments
One of the major challenges in the context of the Cosmic Microwave Background (CMB) radiation is to detect a polarization pattern, the so called B-modes of CMB polarization, that are thought to be directly linked to the space-time fluctuations present in the Universe at the very first instants of life. To date, several challenges have prevented to detect the B-modes partly because of the lower sensitivity of the detectors. Our own Galaxy is observed in this context as a foreground contamination. However the awareness of improving the modeling of its polarized emission has been constantly increase not only to assess the cosmological signals but also to provide new insights onto the Galactic magnetic field probed with the Galactic polarized emissions, e.g. synchrotron and thermal dust. This is particularly relevant in order to better characterize the foreground contamination for future CMB experiments (e.g. SO, LiteBIRD, CMB-S4 ), where high sensitivities are expected to be achieved
Astro-Meet
This year we re-start our bi-weekly journal club where we will chat on the latest astrophysics news and discoveries.
Join us at the Telegram channel ->-> https://t.me/+k-rqzDq1Isw0Zjc0 we’ll use it to communicate our meetings and the discussion topics .
Meetings are on Wednesdays at 14:15 in aula F (DFA).
== BYOM@OACT ==
Bring-Your-Own-Mug at the Osservatorio Astrofisico.
Similarly to the Astromeets we will have meetings also at the Observatory , where you will have the opportunity to chat and meet the INAF researchers in Catania. Bring your mug, coffee will be on me !
Meetings are on Tuesdays at 14:15 in aula Ovest (OACT). They will be announced with the very same telegram channel (linked above).
