We are a group of theoretical physicists striving to better understandthe fundamental laws of nature
My research focuses on theoretical particle physics and cosmology. It moves along the edge of these fields as well as of holography and combinatorics to understand the fundamental rules constraining physical processes at ultra-high energies - much higher than any experiment on Earth and characterizing the early stage of our universe - and their underlying mathematical structures. In particular I am leading a program devoted to apply both phylosophy and methods developed for scattering amplitudes to understand the structure of quantum mechanical observables in cosmology. It aims to understand how to extract fundamental physics out of them as well as how the properties considered as foundational in particle physics emerge from more fundamental principles.
My current research focuses on Wilson loops and the computation of Feynman integrals. Our work on scattering amplitudes brings together researchers from multiple disciplines and backgrounds. Our combined efforts aim to provide a better understanding of the forces that are essential to our world. This is what motivates me to contribute to this fascinating field.
My research area is at the interface of elementary particle physics and quantum field theory. What fascinates me especially is that ideas coming from different scientific communities, such as collider physics, string theory, conformal field theory, and mathematics help to bring about advances. As the principal investigator of the ERC-funded project 'Novel structures in scattering amplitudes', I am excited both to help guide young scientists to interesting research questions, and at the same time to learn from their fresh perspectives.
My research is oriented towards understanding analytical properties and singularities of scattering amplitudes. Currently I am focused on Landau equations which determine the location of the singularities in scattering amplitudes.
In my research, I follow the path from the first principles of quantum field theory to the realistic description of particle scattering in collider experiments. I employ a combination of mathematical insights and analytical and numerical methods to obtain precise theoretical predictions for the phenomenology of particle collisions at high energies. This phenomenology encodes the key information for unraveling the most fundamental laws of the universe.
My main research interests are focused on the physical and mathematical aspects of scattering amplitudes in gauge theories, in particular, towards the development of modern techniques for the calculation of scattering amplitudes. I look forward to understanding the physics that emerges from colliders, like LHC at CERN. I am especially interested in having a pure four-dimensional framework to compute relevant observables useful for the latter. Moreover, I am interested in applying these modern techniques developed primarily for gauge theories to effective field theory approach to general relativity. Currently, I am considering fifth post-Newtonian corrections to the Newton potential to higher orders.
In my research I focus on studying the connection between scattering amplitudes and Wilson loops in conformal field theories and use integrability techniques and ideas to compute these quantities outside of the perturbation regime. These ideas might one day be extended to non-conformal theories like quantum chromodynamics (QCD), which would give us the ability to compute physical quantities in regimes that are inaccessible to conventional quantum field theory techniques and help us gain a deeper understanding of the fascinating connection between gauge theories and string theory.
As a high-energy physicist, there are three major research questions that I find intriguing: What are the best observables to measure in order to probe the underlying quantum theory? Can the observables be computed reliably in perturbation theory? What are the most efficient ways to compute them? To address these questions, I work on problems that fall into a few different
categories: event shapes, in particular, energy-energy correlators, soft/collinear factorization and
violation of scattering amplitudes, as well as novel tools for computation of Feynman loop integrals by the method of differential equations.
My primary objectives are to understand the connection among gauge theories and make precise theoretical predictions through computing radiative corrections to scattering amplitudes and observables employing state-of-the-art techniques.
I work on the calculation of multi-loop Feynman integrals and scattering amplitudes. I am also interested in integrability in quantum field theory, correlations functions in the maximally supersymmetric Yang-Mills theory, and applications of the conformal symmetry.
The study of Feynman integrations is essential as their computation allows us to link theoretical predictions to experiments. I am currently interested in the study of the analytic properties of these Feynman integrals following the aim of computing scattering amplitudes in a perturbative approach.
My primary research interest is the calculation of scattering amplitudes in gauge and gravity theories, and of the Feynman integrals appearing in them. The scope of my work is to use and develop innovative methods for their analytic calculation and to study their mathematical properties and symmetries. Currently, I am involved in the computation of the amplitudes for five-particle processes at two-loop order, and in the study of the implications of conformal symmetry for scattering amplitudes in general.
