Research Interests

I grew up in a small village near the Uni. When I was young, I was watching the night sky, not only to count the stars. Thus, I studied Cosmology. The main topic of my research is the ΛCDM model and possible deviations and/or extensions of it. Modified theories of gravity and compact objects, such as gravastars are some of them.
