Invited researchers

The visitor programme represents the institute’s most important scientific activity. Each year, around 200 researchers are selected by the Scientific Council, after an application procedure. Drawn by the spontaneous and sometimes unexpected interactions that the Institute makes possible and encourages, visitors stay on average for 2.5 months.
Associated professorships provide considerable flexibility for organising scientific activities, with the possibility of inviting collaborators and organising events, and chair holders can stay for longer periods at the Institute.

My current research focuses on low dimensional quantum field theories and their gravitational duals. I have been interested in mapping out the relationship of various kinds of singularities that appear on either side of the holographic duality. I am also interested in understanding whether reformulating various singular phenomenon in information-theoretic terms may shed some new light on these problems. I am also involved with work in string cosmology and the Weak Gravity Conjecture.
