Ronniy Joseph, mentee in the 2019 Energy-Minerals Resources program in WA (Curtin University)

Ronniy Joseph was born and raised in the Netherlands, growing up in a country heavily involved in radio astronomy. After obtaining a Bachelor of Science in Astronomy at the University of Groningen, and a Master of Science in Astronomy at Leiden University, he decided to pursue a PhD close to the heart of the largest radio telescope in the world; the Square Kilometre Array (SKA). This brought him to the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) in Perth.

Supported by the ARC Centre of Excellence For All-Sky Astrophysics in 3D (ASTRO3D), his research aids to uncover the birth story of the very first stars, galaxies, and black holes in the Universe. He works on the fine tuning of the many thousands of antennas of the SKA and its precursors that aim to detect faint old radio signals that tell us the history of the Universe. Using radio interferometry, mathematical statistics, Fourier analysis, and numerical simulations, his work predicts the effect of antenna flaws on our ability to detect those signals. His most recent paper was presented at the Science at Low Frequency conference in Nagoya, Japan.

In between research Ronniy invests his time in the next generation of astronomers, sharing his passion for astronomy through astronomy outreach at public events, school visits in metropolitan and regional areas of WA, hosting high school work experience students, assisting with undergraduate courses, and mentoring junior PhD students.
