III Wing

We are pleased to invite you to the RBI Colloquium: Gravitational Waves: the Theorist’s Swiss Knife by Professor Mairi Sakellariadou, President of the European Physical Society and Professor of Theoretical Physics at King’s College London, United Kingdom. The lecture will take place on Tuesday, 16 December 2025 at 2:00 PM in the III Wing lecture hall, Ruđer Bošković Institute.

After a short introduction to the stochastic GW background I will highlight how one uses currently available LIGO/Virgo/Kagra data not only to learn about compact binaries and the large-scale-structure of our universe, but also to constrain particle physics models beyond the Standard Model, modified gravity proposals, and even quantum gravity theories.

Mairi Sakellariadou is professor of theoretical physics at King’s College London and the current president of the European Physical Society. Her research follows two main directions: (I) use gravitational waves to probe the Universe and test fundamental theories, (II) use quantum gravity proposals to build cosmological models and in return use current observational and experimental data to test the validity of such proposals. Professor Sakellariadou is a member of several international collaborations, namely: LIGO Scientific Collaboration, GEO 600, LISA consortium, Einstein Telescope Observational Science Board, MoEDAL experiment, Square Kilometer Array Telescope project, and Euclid consortium. She is also founding committee member of the International Society for Quantum Gravity (ISQG), member of the Foundational Questions Institute (FQXi), Editor-in-Chief of General Relativity and Gravitation (Springer) and elected member of the Initiative for Science in Europe (ISE).
