I am a postdoctoral researcher at the Max Planck Institute for Radio Astronomy (MPIfR). My primary research interest is the role of magnetic fields in the interstellar medium, as well as in the evolution of galaxies.

I am a key member of multiple large survey projects conducted with the precursor telescopes of the upcoming Square Kilometre Array (SKA), specifically the MeerKAT and the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescopes. These surveys include the MPIfR-MeerKAT Galactic Plane Survey (MMGPS), the Polarisation Sky Survey of the Universe’s Magnetism (POSSUM), and the Galactic ASKAP HI survey(GASKAP-HI).

In addition, I am a frequent user of other world-class radio telescopes such as the Very Large Array (VLA), the Australia Telescope Compact Array (ATCA), and the Parkes “Murriyang” 64-m Radio Telescope.

This webpage is currently a work in progress.
