Profile

I joined the Centre for Theoretical Physics (CTP) in 2018. Previously, I held research positions at Caltech, at University of Rome, Tor Vergata, and at CTP in QMUL. I received my PhD at Brown University, and I did my undergraduate and graduate studies at Zhejiang University.

Teaching

I currently teach a module `An introduction to strings and branes`. The course is a basic introduction to String theory and Branes.

I also supervise undergraduate and master projects.

Correlators and scattering amplitudes: AdS/CFT correspondence and exact results
 

Scattering amplitudes are among the most fundamental observables in quantum field theory and string theory. In recent years, hidden structures within scattering amplitudes have been uncovered, and powerful computational methods have been developed. These advancements have significantly enhanced our understanding of both quantum field theory and string theory.

According to the AdS/CFT correspondence, scattering amplitudes in AdS space are equivalent to correlation functions in the dual CFT. Recently, exact methods have been developed for computing certain correlators in supersymmetric CFTs beyond perturbation theory. These new exact results have been shown to match the exact results of superstring amplitudes.

This project will focus on these recent and remarkable developments in this rapidly evolving research field. It aims to further develop these powerful tools for both amplitudes and CFT correlators, as well as to understand their connections within the context of the AdS/CFT correspondence.

Requirements: knowledge of Quantum Field Theory, String Theory and Supersymmetry at the level of a Master course.
