Κάλλια Πετράκη

I am a theoretical particle physicist, and I work as a researcher at the Laboratoire de Physique Theorique et Hautes Energies (LPTHE [fr]) in the Sorbonne University, located at the Jussieu campus in Paris. I am also part of the theory group of Nikhef [nl], the Dutch National Institute for Subatomic Physics, located in the Science Park, in Amsterdam.

I am currently the PI of the grants

Research Interests

I am interested in physics beyond the Standard Model, mostly in the context of dark matter, the matter-antimatter asymmetry of the universe and neutrinos. I have worked on bound states in dark matter phenomenology, self-interacting dark matter, asymmetric dark matter, the matter-antimatter asymmetry, and sterile neutrinos. Within these topics, my work includes aspects of model-building, early-universe cosmology, dark-matter indirect detection, dark matter in stars and collider signatures.
