Our research interests focus on a deeper understanding of the gravitational force at very small distance scales (quantum gravity and the very Early Universe) and at cosmological distance scales (dark energy). Due to the expanding nature of our Universe, these problems are interrelated in an intriguing and challenging way. String Theory is by far the most promising candidate theory of quantum gravity (although other interesting approaches such as loop quantum gravity and causal dynamical triangulations are explored as well). On the other hand, modified gravity models such as Massive Gravity change the workings of gravity at large distance scales and are candidates to solve the dark energy mystery.
The focus point in my research is the study of a new class of extended objects in String Theory, called Exotic Branes. These new objects contain information about the geometry underlying String Theory, called String Geometry, which is an extension of the Riemannian geometry of General Relativity. String Geometry and Exotic Branes are relevant for the embedding of realistic inflationary scenarios into String Theory and for a deeper understanding of the Black Hole interior.
The focus point in my present research is nonrelativistic gravity in (i) nonrelativistic string theory and (ii) effective field theory. The aim in the first case is to investigate the status of nonrelativistic quantum gravity and nonrelativistic holography while in the second case the goal is to explore applications to condensed matter systems such as the fractional quantum Hall effect.
