Before joining the Faculty of Health Sciences as a Research Support Officer, Josef Borg successfully completed a PhD within the Institute of Space Sciences centering on radio astronomy, and in particular, the calibration of radio interferometers. He worked on the BEST-2 array at the Medicina Radio Observatory, as well as on the upcoming Square Kilometre Array telescope in Australia and South Africa. These projects involved the development of pipelines for handling of data coming from these telescopes, and eventual calibration of these telescopes using such observations. During the course of his doctoral studies, he has also supervised a number of projects, including a B.Sc. project focused on the observation of exoplanets.

Previously, he also read for his undergraduate degree at the University of Malta, within the Faculty of Science, for a B.Sc. in Biology and Chemistry (Hons.). His undergraduate dissertation centered around the simulation of the evolution of the atmosphere of Saturn's moon, Titan, as the Sun becomes a red giant.

Josef Borg is now working as a Research Support Officer on the TargetID – Novel Drug Targets for Infectious Diseases project, within the Department of Applied Biomedical Science at the faculty of Health Sciences.
