Gravity is the oldest force known, yet the least understood. The CEICO Gravity group works on developing a more complete description of gravity at a fundamental level both on microscopic and on cosmological scales. 

From the fundamental theory perspective, our group members work on Higher-Spin gravity and Black Hole entropy calculations within the framework of String Theory. We are also investigating whether any evidence of new gravitational physics may be present in the region of space-time with the highest curvature: black holes and compact stars. As such, we are interested in calculating how these objects change in the presence of new gravitational degrees of freedom and how future observations may be able to constrain them.

At the opposite side of the spectrum, we study effective ultra low-curvature theories of gravity in order to understand their phenomenology and whether such theories can consistently model the late-time acceleration of the expansion of the universe.
