I recently defended my PhD as an IMPRS fellow and I am a postdoc at the Max-Planck-Institute for Astronomy (MPIA) in Heidelberg. As a member of Fabian Walter’s group, I work on high-resolution studies of the molecular gas in nearby galaxies. In particular, I study interplay of star formation and stellar feedback with the interstellar medium. A significant part of my work is interferometric imaging and more general aspects of multi-dimensional analysis of the imaged high-resolution data cubes.

I started astronomical research in 2013 with my Bachelor’s thesis on multi-scale cleaning in radio interferometric imaging and carried out several projects as a research assistant (“HiWi”). These projects included, for instance, data reduction and imaging of JVLA observations that targeted nearby galaxies in atomic hydrogen (HI). Since 2015, I am a member of the SWAG team (Survey of Water and Ammonia in the Galactic Center), for which I developed calibration and imaging pipelines as part of my Master’s thesis (2016). Furthermore, I derived new, detailed gas temperature maps from ammonia hyperfine structure fitting of the Central Molecular Zone of the Galactic Center to test and confirm the hypothesis of a triggered star formation sequence. During the work for my PhD thesis, I became an expert on reducing and imaging complex ALMA observations such as the 2 pc imaging of the starbursting center of NGC253.
