Professor Mairi Sakellariadou gained her Bachelor Degree (B.Sc.) in Mathematics from the University of Athens. She then studied Astrophysics  at the Institute of Astronomy, University of Cambridge. She obtained a Certificate of Post-graduate Studies and a Master of Sciences (M.Sc.). During her stay in Cambridge, she was member of Trinity College and President of Post-graduate students.   She then continued her studies at Tufts University, in Massachusetts (USA). She obtained a Master in Sciences and a Doctor of Philosophy (Ph.D.) in Physics.  Since completing  her Ph.D, Professor Sakellariadou has held research positions at the Université Libre de Bruxelles, Université de Tours, Université Pierre and Marie Curie (Paris VI), Universität Zürich, Université de Genève, and CERN. She was Associate Professor at the University of Athens, before joining King’s in 2005 as a reader. She was appointed Professor of Theoretical Physics in 2011.


Professor Mairi Sakellariadou's field of research is theoretical physics and cosmology, with emphasis on the physics of the early universe. Her research stands at the interface between cosmology, theoretical particle physics and gravitational theories, testing the most advanced theories against the plethora of astrophysical, cosmological and high energy physics data. Her  research activity spans over the following directions:

  • Noncommutative Spectral Geometry;
  • String/M-theory Cosmology;
  • Loop Quantum Cosmology;
  • Group Field Theory;
  • Gravitational Waves;
  • Cosmic (super)strings

Her aim is to keep contributing to the collective scientific effort to uncover the early stages of the evolution of our universe and provide the means to test fundamental theories, using the early universe as our (unique) laboratory.
