Jun.-Prof. Dr. Christopher J. Riseley
Junior Professor of Radio Astronomy at
Ruhr-Universität Bochum

I am a Junior Professor of Radio Astronomy at the Ruhr-Universität Bochum. My research involves using radio telescopes around the world to study clusters of galaxies. In particular, I am interested in answering several key science questions related to diffuse radio sources in clusters: the canonical relics, haloes, and mini-haloes, as well as all the weird and wonderful sources being discovered by the maturing Pathfinder and Precursor instruments for the Square Kilometre Array (SKA).

I specialise in long-wavelength radio astronomy, with a particular focus on exploring data from the LOw-Frequency ARray (LOFAR), the Murchison Widefield Array (MWA), the Australian Square Kilometre Array Pathfinder (ASKAP), and the MeerKAT telescope in South Africa.

Outside of my own research, I am the MWA Principal Scientist, a role I have held since 2021, and a former member of the Astronomical Society of Australia (ASA) Early Career Researcher (ECR) Chapter Steering Committee (2021 - 2023).
