At a very basic level, scientific observation is just a process by which we are provided with a list of numbers describing the outcomes of their experiments. Scientists attempt to find a mathematical model which can reproduce correlations between the various numbers in the list, but arguably the list, and the information it contains, is more fundamental than the model. This perspective was termed 'it from bit' by John Wheeler in 1986, and my main interests lie in applying it to quantum gravity. In particular, I try to think about how this approach is informed by experimentally verified properties of gravity, such as its low energy behavior in the semiclassical limit. The relevance of objects such as black holes in this regime allow us to ask very sharp questions about the underlying information. More generally I am also interested in what we can learn from specific models that describe the ultraviolet physics.

Recent developments in different approaches to quantum gravity seem to suggest a very intriguing picture of spacetime as a many-body quantum system whose physical properties result from the correlations and exchange of information among its microscopic texture. My main interests lie in further exploring such a picture and its foundational implications, with a multi-disciplinary and possibly approach-independent attitude. This consists first of all in investigating how the structures characterizing spacetime at classical and ultimately quantum level can be inferred from general ideas and techniques borrowed from statistical mechanics, information theory and thermodynamics. Second, I am interested in the lessons and insights that we can learn from implementing the above perspective in specific microscopic models of spacetime. In this sense, black holes and cosmological systems can offer promising scenarios where these questions can be addressed in a simplified setting.
