Research Interests

During my PhD, I studied the phenomenon of multiple stellar populations (MSPs) in globular clusters. These populations, characterized by variations in some chemical elements, challenge the classical view of globular clusters as simple stellar systems. I developed a robust method to assess the morphology of globular clusters and the spatial distribution of their MSPs. I also investigated one of the proposed formation scenarios for MSPs involving nucleosynthesis in black hole accretion disks.

Another core aspect of my work addresses the environmental impact of astrophysical infrastructure. As a postdoctoral researcher at the University of Vienna, I study the sustainability of the Wide-field Spectroscopic Telescope (WST), a conceptual 12-meter-class facility. I am using a life cycle assessment to analyse and evaluate the environmental impact of the WST and explore choices that minimize impact while maintaining scientific performance.

In parallel, I engage with the broader intersection of science and sustainability. I designed and currently teach a course titled Sustainability in Academia, which introduces students to the challenges faced by academia and explores how scientific institutions can contribute to sustainability.

I am also a steering group member of Astronomers for Planet Earth, a grassroots movement aiming at addressing the climate crisis from the unique perspective of our field.
