Chiara Boccato

I am a researcher at the University of Pisa (since May 2024).

My research interests are centered on the mathematical study of many-body quantum systems. I focus on dynamical and spectral properties, and on the derivation of effective theories describing their emergent collective behavior.

My CV is available here. Here you find my Scopus and Google Scholar pages.

I am the local coordinator of the project PRIN 2022 "Interacting Quantum Systems: Topological Phenomena and Effective Theories".

This spring semester 2025 I am giving the PhD course "Mathematical methods of quantum mechanics", open to Master's and PhD students. A presentation of the course here. More details here (frequent updates).
