Dr. Joseph Caruana read for a B.Sc. (Hons) in physics and mathematics at the University of Malta. Following this, he embarked on doctoral research in the high-redshift group at the University of Oxford. There he read for a DPhil in astrophysics as a Marie Curie research fellow in ELIXIR - a network associated with the NASA/ESA James Webb Space Telescope NIRSpec Instrument. While at Oxford he tutored Cosmology & General Relativity at Christ Church.

Between 2012 and 2016 he was a postdoctoral researcher in astrophysics at the Leibniz Institute for Astrophysics Potsdam (AIP), where he worked as a member of the Galaxies & Quasars group and the MUSE consortium.

In 2016 he joined the University of Malta as lecturer in the Department of Physics and the Institute of Space Sciences & Astronomy (ISSA), teaching Nuclear Physics and Astronomy & Cosmology.

Amongst other study units, he currently teaches Geometric Optics, Physical Optics, Astronomy and Cosmology, and Philosophy of Science.

His main research revolves around observational cosmology, particularly galaxy formation & evolution, and galactic dynamics.
  • Observational Cosmology
  • Cosmic Reionization
  • Galaxy Formation and Evolution
  • The Universe at High-Redshift
  • Lyman alpha emission
  • Galactic Dynamics
