I am Nico Schuster and I currently work as a Postdoctoral Researcher at the Centre de Physique des Particules de Marseille (CPPM) in Alice Pisani’s research group. I am active within several current and upcoming cosmological surveys: DESI, Euclid, the Vera C. Rubin Observatory (LSST), and the Wide-Field Spectroscopic Telescope (WST).
In my research, I explore the underlying properties of our Universe by using cosmic voids, the expansive, low-density regions between galaxies, to test fundamental physics. My research focuses on the theoretical modelling and interpretation of matter and galaxy distributions in and around voids, with the goal of sharpening cosmological constraints and establishing rigorous models for the next generation of galaxy surveys. In parallel, I study the imprints of dark energy, modified gravity, massive neutrinos, and other physical theories on cosmic voids, developing new observables tailored to disentangle their respective signatures.
Before Marseille I completed my PhD at LMU Munich, where I studied the fundamental properties of cosmic voids and advanced the modeling of their statistics to increase the potential of voids as cosmological probes. This PhD project was supervised by Nico Hamaus and Jochen Weller.
Alongside my research, I build interactive visualization tools that serve the public and the cosmology community, bridging the gap between teaching, outreach, and research by making complex ideas accessible to everyone. You can try them on the Tools page.
