My research is on mathematical physics, broadly speaking, with a focus on quantum field theory and string theory, and their connections to modern geometry and topology.

**Papers**

A list of my papers, with links to PDF files, can be found here or here. Below you can find some review papers which are not easily accessible on the internet and provide a useful introduction to my research.

**Quantum theory and non-perturbative effects**

In 2017, the 7th Itzykson seminar at IHES was devoted to the topic "Resurgence and quantization". I was asked to give a survey talk on the subject. You can find the write-up of the talk here. The video recording can be watched here.

**Mathematics and string theory**

Some time ago, Claudio Bartocci asked me to write a chapter for the Einaudi encyclopedia of mathematics on the relation between string theory and mathematics. The text was translated into Italian by Ugo Bruzzo. Although it is slightly outdated, it seems to be still useful. You can download it here.

**Stringy geometry and emergent space**

This is my contribution to the book "New spaces in mathematics and physics", based in turn on a workshop organized in Paris in 2015 by Mathieu Anel and Gabriel Catren. It can be downloaded here.
