Bio sketch 

Roberto was born and grew up in the Italian speaking part of Switzerland. After obtaining an MSc(hons) in Physics from ETH Zurich and a PhD in Theoretical Physics from the University of Geneva, he moved to Oxford where he was the Lockyer Fellow of the Royal Astronomical Society at Oxford University, and a Junior Fellow of St Anne's, before being appointed at Imperial in 2008.  

Roberto is a passionate science communicator and the recipient of numerous awards for his research, outreach and art and science collaborations, including the Lord Kelvin Award of the British Association for the Advancement of Science and the Michelson Prize of Case Western Reserve University.

His award-winning first book for the public, "The Edge of the Sky: All you need to know about the All-There-Is", endeavours to explain the Universe using only the most common 1,000 words in English. Roberto was named as one of the 100 Global Thinkers 2014 by Foreign Policy magazine (Nov 2014), for "junking astronomy jargon". 

He is a co-founder and director at Data Fusion Consultants, offering statistical consultancy and custom-made data analysis solutions. He works as a scientific consultant with museums, writers, film makers and artists, providing the help and support they need to make their artistic creations scientifically sound.
