About Me
Research Interests
I am an observational astronomer interested in extragalactic astrophysics and cosmology. My favourite method for gaining empirical insights into these topics is integral field spectroscopy.

- 2022-2023: Visiting researcher at Leiden Observatory (Netherlands) with the ESO Fellowship.
- 2019-2023: Fellowship with the European Southern Observatory in Santiago (Chile).
- 2016-2019: Post-Doc with Matthew Hayes at the Institute for Astronomy at Stockholm University (Sweden).

Software
LSDCat
LSDCat is a conceptually simple but robust and efficient detection package for emission lines in wide-field integral-field spectroscopic datacubes. The detection algorithm is based on a 3D matched-filtering approach for emission line objects. The software also measures fluxes and extents of detected lines. LSDCat is implemented in Python, with a focus on fast processing of large data-volumes.
