Research

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.
