Dr. Jurjen de Jong

Profile Picture

I am a researcher, radio astronomer, and software developer at Leiden Observatory and ASTRON. My work focuses on developing and improving data-reduction strategies and techniques for automated processing of radio interferometric data from the European LOw Frequency ARray (LOFAR) to produce wide-field sub-arcsecond resolution images on HPC clusters from Surf. Scientifically, I am also interested in studying the cosmic evolution of radio galaxies and the mergers of galaxy clusters.

Previously, I have developed data-driven machine-learning pipelines at Matrixian Group, interned as a mathematical astronomer at the European Space Agency and as a mechanical engineer at EPPM, and wrote popular scientific articles for Scientias. My educational background includes bachelor’s degrees in Mathematics and Physics, an MSc in Mathematics, an advanced MSc in Space Studies, and a PhD in Radio Astronomy. I am also a co-founder of Stamily, which is a non-profit organisation that supports and connects people around the world who happen to have a stutter.
