He occupied postdoctoral positions at Berkeley and CERN, before returning to the UK to join the faculty in the astrophysics department at the University of Oxford as a research fellow and lecturer.[5] He became Professor of Astrophysics there in 2008. He has been director of the Programme on Computational Cosmology at the Oxford Martin School since 2010, and also runs an astrophysics 'artist in residency' programme. Ferreira regularly lectures at the African Institute for Mathematical Sciences, and has frequently appeared on TV and radio as a science commentator.
Ferreira's main interests are in general relativity and theoretical cosmology. He has authored more than 100 publications in peer-reviewed scientific journals.[6] With Michael Joyce, in 1997 he was one of the first to propose quintessencescalar field models as a possible explanation of dark energy. Ferreira was also a member of the MAXIMA and BOOMERanG balloon-borne CMB experiments, which measured the acoustic peaks of the CMB. He is currently involved in several proposals to test general relativity using the Euclid spacecraft and Square Kilometre Array radio telescope.
Media
Ferreira is a regular contributor to the scientific press, including Nature, Science, and New Scientist, and has authored two popular science books on cosmology and the history of general relativity. One of them, The Perfect Theory, was shortlisted for the 2014 Royal Society Winton Prize for Science Books. He regularly appears on TV and radio to discuss astrophysics and cosmology news stories, and has contributed to several science and mathematics documentaries for the BBC, Discovery Channel, and others. In 2016 he serves on the editorial board of the Open Journal of Astrophysics.[7]
