My research focuses on mathematical aspects of two of the many existing approaches to quantum gravity:

– random tensor models & random matrix models
– random noncommutative geometry (à la Connes)

Also, I am interested in the relation among these two topics and: non-perturbative quantum field theory, functional renormalization group, topological recursion, large-N limits, free probability, random matrix theory.

More on it and my CV are found here.

From 2015 to 2020, I completed my bachelor's and master's degrees in physics at the University of Pisa. During the master thesis I worked under the supervision of Alessando Vichi on A large-N tensor model with four supercharges.

In 2021 I started my PhD under the supervision of Razvan Gurau and Dario Benedetti at the University of Heidelberg, where I am currently working.

My main fields of interest are in Quantum Field Theory, Renormalization, Large-N theories and Conformal Field Theory.

Hannes Keppler

I am a PhD student in the mathematical physics group of Razvan Gurau at the ITP, Heidelberg University. I also did my undergraduate studies in Heidelberg from where I graduated in 2022. During Bachelor and Master I was focusing on theoretical high energy physics, and topology and geometry in physics.

In my master thesis, also supervised by R. Gurau, I studied Duality of Orthogonal and Symplectic Colored Random Tensor Models.

My research interests include: Cominatorics and geometry of random tensor models, as well as methods for Quantum Field Theory beyond perturbation theory, such as Lefschetz-Thimbles and Borel summation.
