I study cosmology and gravitation: the dark components of the Universe, the nature of gravity, and their observational consequences.

01 / Research

The Universe,
still in question.

Most of the energy content of the Universe is associated with dark matter and dark energy, whose fundamental nature remains unknown. My work explores theoretical approaches to these open questions and their observational consequences.

Dark matter & dark energy
The cosmological constant problem
Modified theories of gravity
Alternatives to particle dark matter
Large-scale structure & cosmological tensions
Gravitational lensing
Physics of the primordial Universe

02 / Teaching

From research
to the classroom.

Cover of Lecture Notes in Cosmology, first edition

Lecture Notes
in Cosmology

From the expanding Universe and its thermal history to cosmological perturbations, inflation and the cosmic microwave background.

The extended and updated notes are available on arXiv and form the basis of the forthcoming second Springer edition.
