Biographic Notes
José Afonso is a researcher at IA and at the Physics Department of the Faculty of Sciences of the University of Lisbon. He was awarded a first degree in Physics (1996) and a MSc in Astronomy and Astrophysics (1998) by the Faculty of Sciences of the University of Lisbon, and a PhD in Astrophysics (2002) by the University of London - Imperial College of Science, Technology and Medicine. He/She is a member of IA since 2014.

Current research interests focus on observational studies on galaxy formation and evolution from the highest redshifts. The research makes use of some of the deepest astronomical surveys available to try to understand the evolution of the star-formation and Active Galactic Nuclei phenomena in galaxies, along with the formation of (proto-)clusters and large scale structure. A particular emphasis exists on the development of the next generation of radio surveys (e.g., The Evolutionary Map of the Universe - EMU, that will use the upcoming ASKAP telescope).

He is the current Coordinator of IA, is the Co-Principal Investigator for MOONS, a Multi-Object Optical and Near-infrared Spectrograph for ESO’s VLT, under construction (first light planned for 2021), and represents Portugal in the Wide Field Imager Consortium Board for ESA’s mission Athena (launch planned for 2032). He is also a Core member of the Square Kilometre Array Science Working Group: Continuum Science Team, and is the representative of the Portuguese ALMA Centre of Expertise in the European ALMA Regional Centre.
