Astrochemistry, Star Formation, Interstellar Medium & Shocks
Hi, I’m Kasia
I’m an astrochemist, which means that in my work I use molecules as messengers, revealing the physical and chemical conditions and histories of different cosmic environments. I am especially drawn to chaotic, extreme regions like the Galactic Center of the Milky Way or distant galaxies with active galactic nuclei and intense star formation.Current work
I’m a postdoctoral researcher at Leiden Observatory in Prof. Serena Viti’s group, where I am one of the developers and maintainers of UCLCHEM, a time-dependent gas-grain chemical code. Lately, I’ve been focused on the Milky Way’s Central Molecular Zone, a turbulent, molecule-rich region that constantly challenges our understanding of interstellar chemistry.A step back → PhD work
During my PhD, I built “galaxy-in-a-box”, a Python-based model that predicts molecular emissions from active star formation in galaxies. Ultimately, I wanted to explore the era when the Universe formed most of its stars (Cosmic Noon, ~10–11 billion years ago), understand how star formation contributes to galactic emission, and see if we could identify new tracers of these processes. The project bridges theory and observations without relying on heavy simulations, offering a more direct way to interpret molecular feedback. The project is currently on hold, with further development planned.A bit more about me
Before I found myself in astrophysics, I studied filmmaking in London, dreaming of becoming a director. That path didn’t quite fit, but it shaped how I approach problems creatively and notice patterns others might miss. Science eventually pulled me in, and I ended up earning a PhD in astrophysics from the University of Copenhagen. As a first-generation academic, it was a leap, but one I’m glad I took.Creativity remains part of my life. I am an active street photographer, with work featured by Samsung, Polaroid, the Danish Architecture Centre, BuzzFeed. I’m also super into curating music playlists (I know it sounds cheesy, but since I’ve never become a DJ, this is my compromise) and maybe one day I’ll host a show on an independent online radio. Beyond the arts, I’m a huge mindfulness and mental health advocate. And last but not least, I’m a coffee nerd - the funkier, the better - but I don’t judge anyone else’s cup.
