About

Sergei Odintsov is a Research Professor at ICREA and ICE (CSIC-IEEC) in Spain. His research areas include modified gravity, dark energy, and cosmology, with a focus on the implications of recent findings in rainbow-deformed f(R) gravity and its compatibility with observational data. He has published extensively on topics such as black hole thermodynamics, entropic cosmology, and the dynamics of gravitational waves.
