Matteo Parisi

Matteo Parisi is the head of the Algebraic Combinatorics and Fundamental Physics Unit. His research lies at the intersection of algebraic combinatorics and high-energy physics, where he pursues a program in which quantum observables in particle physics and cosmology arise from combinatorial and geometric structures. He investigates how fundamental questions in quantum field theory and related areas of string theory connect with ideas of total positivity in algebraic combinatorics. 

A central focus of his work is scattering amplitudes—notably in N=4 super Yang–Mills theory—and their links with the positive Grassmannian, the amplituhedron, and cluster algebras. He also seeks to elucidate the singularities and analytic properties of scattering amplitudes and Feynman integrals, for example through Landau analysis. 

His research further intertwines with matroid theory, non-linear algebra, and areas of geometry at the interface with combinatorics, including algebraic, tropical, convex, and the emerging field of positive geometry. At the core of Parisi’s goal is building a shared language between mathematics and theoretical physics, with the aim of advancing both fields together.
