I am interested in various aspects of effective field theories, including the construction of operator basis, applications in neutrino physics and collider physics.

My current work consist in the automation of the renormalization of the electroweak sector in the SMEFT. I am also interested in gauge invariance in both the SM and GR and its connection with non-local effects.

Research statement
I am working on Effective Field Theory (EFT) at colliders mainly in top and electroweak sector. Recently, I have been focusing on the interplay between PDF and EFT fits and on the computation of NLO QCD corrections for the SMEFT.
I am the author of NLOCT and one of the FeynRules authors.
I am also investigating how the photon polarisation in cosmic rays can be used to probe BSM physics.

Active projects
EFT@NLO
Céline Degrande, Fabio Maltoni

Implementation of the SMEFT at NLO in QCD in the Feynrules MadGraph5_aMC@NLO chain and phenomenological studies

External collaborators: Cen Zhang, Celine Degrande.
FeynRules
Céline Degrande, Fabio Maltoni

An automated framework for BSM phenomenology that allows one to compute Feynman rules from a Lagrangian.

External collaborators: Céline Degrande (CERN) Benjamin Fuks (Jussieu).
PDF4EFT
Céline Degrande

The project aims at simultaneously fit PDF and the SMEFT. The first step was the introduction of 4 four-fermion operators in the DIS fit. The next steps are the inclusion of other relevant operators and to increased the data sets used.

External collaborators: Maria Ubiali, Stephano Carrazza, Juan Rojo, Shayan Iranipour.
