Astrochemistry, Star Formation, Interstellar Medium & Shocks

Who am I?
Hi, I’m Kasia—an astrophysicist by both passion and profession. I spend my days exploring the chemistry of our galaxy and beyond, blending observational data with modeling to unravel the secrets of the universe. In other words, I look at molecules to tell the story of cosmic environments—how they evolve, interact, and shape the universe.What am I doing?
Right now, I’m a postdoctoral researcher at Leiden Observatory, working in Prof. Serena Viti’s group. I’m one of the core developers and maintainers of UCLCHEM, focusing on gas-grain chemistry in extreme conditions. Lately, I’ve been particularly obsessed with the Central Molecular Zone of the Milky Way—a chaotic, turbulent, but incredibly exciting region that keeps challenging our understanding of interstellar chemistry.What was my PhD about?
During my PhD, I built galaxy-in-a-box, a Python-based model designed to predict molecular emissions from star-forming galaxies. The goal? To capture the signatures of ongoing star formation using fundamental astrophysical principles—without the heavy computational costs of MHD simulations. It’s a tool that bridges the gap between observation and theory, helping us interpret the chemistry of galaxies in a practical and accessible way.Scientific interests
I’m fascinated by the interstellar and circumgalactic medium—the vast, dynamic environments where stars are born, live, and die. The universe is a complex web of interactions, and molecules are its messengers. By studying them, we can trace the physical conditions, histories, and evolution of different regions in space.Is there more to the story?
Before astrophysics, I had a completely different dream: filmmaking. I studied film in London, aiming to become a director. But something felt off—it wasn’t the right fit. I took a step back, reflected, and realized that my true passion had always been science. Growing up, becoming an astrophysicist seemed like an impossible dream, especially as a first-generation academic. But I took the leap, applied to an astronomy program, and eventually earned my PhD in astrophysics from the University of Copenhagen. Looking back, I wouldn’t change a thing.Outside work
My love for the arts never faded. I’m an avid street and urban photographer, and my work has appeared on album covers, articles, and promotional materials. Some big names—Samsung, Polaroid, and the Danish Architecture Centre—have even shared my photos. Music is another passion, and I still daydream about becoming a DJ someday. Beyond that, I practice mindfulness and advocate for mental health, trying to make space for both the vastness of the cosmos and the depths of human experience.
