Title: Gravitational waves: a new window into the universe and its laws
Abstract: I will discuss the search for gravitational waves and the novel and powerful tool they provide to understand our universe and the laws that govern it. After a short introduction to gravitational waves and the methods to detect them, I will review how we use gravitational waves to test particle physics theories beyond the Standard Model, theories of gravity, early and late universe cosmological models, as well as astrophysics of compact objects. The implications of gravitational-wave detections can hardly be overestimated.

Prof Mairi Sakellariadou, a distinguished scholar in theoretical physics and cosmology, has an illustrious academic and research career beginning with a B.Sc. in Mathematics from the University of Athens, followed by advanced studies in Astrophysics at the University of Cambridge, where she earned a Certificate of Post-graduate Studies and an M.Sc., and was a member of Trinity College and President of Post-graduate students. She furthered her education at Tufts University, USA, acquiring an M.Sc. and a Ph.D. in Physics. Post-Ph.D., she has contributed to research across prestigious institutions globally, including Université Libre de Bruxelles, Université de Tours, Université Pierre and Marie Curie, Universität Zürich, Université de Genève, and CERN, eventually joining King’s College London in 2005, where she was appointed Professor of Theoretical Physics in 2011. She is also editor-in-chief of the journal General Relativity and Gravitation. Her research is mainly focused on searching for new physics through gravitational waves. As such, her work encompasses noncommutative spectral geometry, string/M-theory cosmology, loop quantum cosmology, group field theory and cosmic (super)strings. She is part of the LIGO collaboration and, following the detection of gravitational waves, initiated the EPS gravitational physics division and joined the EPS council. In July 2023, she was elected president of the EPS and subsequently took office in April 2024.
