Current position

I work as researcher at INAF/Osservatorio Astrofisico di Arcetri . Since September 2015 I am the principal investigator and leader of the young research group RESERVOIRS financed by Ministero dell'Istruzione, Università e Ricerca (MIUR) program "Scientific Independence of young Researchers (SIR)".

    2010-2011:     Assistant Research Scientist at Johns Hopkins University (Baltimore, MD - USA)




    2009:     Postdoc at Max Planck Institute for Astronomy (Heidelberg, Germany)




    2006-2008:     PhD Student at University of Padova (Padova, Italy)




Research

A most important and fascinating topic of modern astrophysics is the formation of planetary systems which is my main field of research. I investigate the physical structure and chemical composition of protoplanetary disks where comets, planets and moons are forming at this right moment. Most of my recent work is based on observations with taken with the Atacama Large Millimeter Array (ALMA).

Recent highlights

First detection of the simplest organic acid in the protoplanetary disk surrounding a Sun-like young star
We report the first detection of HCOOH (formic acid) in the protoplanetary disk around TW Hya. The formic acid contains a carboxylic group (-COOH), which stands as the basis for synthesis of more complex carboxylic and amino acids used by life on Earth. More specifically, this species is involved in a chemical route leading to glycine, the simplest amino acid, the basis of many proteins

ALMA continuum observations of the protoplanetary disk AS 209
ALMA reveals two dust gaps in the protoplanetary disk around AS 209 in the Ophiucus star forming regions. The two dust gaps are a clear evidence of the interaction between the disk with young (unseen) planets
Fedele, Tazzari, Booth et al. A&A 2018, 610, 24





ALMA reveals dust and gas gaps in the protoplanetary systems HD 169142
ALMA observations of cold gas and dust revealed the presence of gaps and rings in HD 169142. The most plausible explanation is that these pronounced gaps in the gas distribution were carved out by giant protoplanets
