Academic interests

My research centers on understanding cosmic magnetic fields, often through the use of molecules as tracers. I combine observational work with theoretical and modeling approaches. Beyond magnetic fields, I have developed an interest in the fundamental physics of radiative transfer in spectral lines, exploring regimes from the interstellar medium to controlled laboratory conditions. My work has also included studies of molecular chirality in space, theoretical spectroscopy, as well as investigations of how magnetic fields influence Earth atmospheric remote-sensing measurements.

I enjoy thinking broadly about astrophysics and have never confined myself to a single process or environment. My research has spanned (massive) star formation, evolved stars, and protoplanetary disks. More recently, I have expanded my focus beyond the Milky Way: at the Institute for Theoretical Astrophysics of UiO, I investigate the central, most active regions of very luminous external galaxies, exploring how gas moves in and out around the supermassive black hole and how these processes relate to their magnetic fields.

Background

I studied chemistry at Radboud University, where I specialized in theoretical chemistry. I later completed a PhD in astronomy: my thesis is called "Tracing Cosmic Magnetic Fields Using Molecules".

After my PhD, I worked as a Postdoctoral Researcher, splitting my time between Leiden Observatory in the Netherlands, and the Chalmers University of Technology in Gothenburg, Sweden. This position was supported by a Swedish Research Council (VR) International Postdoc Grant.

Since September 2025, I have been employed at the Institute of Theoretical Astrophysics of the University of Oslo as an MSCA Fellow within the DSTrain program.
