Research interests

I am a particle physicist. My mission is to unveil the microscopic laws that govern the fundamental particles and their interactions. I study what these laws could be, and how they manifest as concrete predictions for a multitude of experimental measurements that are being and will be performed at particle colliders. Devising strategies to extract maximal information on fundamental physics laws from the data collected at the Large Hadron Collider is a main focus of my research. Another goal is to identify new pathways for further progress at ambitious future collider projects and in particular at a muon collider of very high energy. I attack these questions by employing and developing theoretical tools for predictions based on the fundamental principles of quantum mechanics and special relativity, combined in what is known as "Quantum Field Theory", as well as statistical and statistical learning tools for comparing the predictions with the experimental data.

Selected research activities

-In 2023, I contributed to the global efforts towards a muon collider by a number of accomplishments
  • I organised two workshop on muon collider physics, at KITP (UC Santa Barbara) and at the University of Pittsburgh, and the Annual Meeting of the International Muon Collider Collaboration.
  • I was the principal editor of the first ever published integrated review on muon collider physics, detector, accelerator physics and technology.
  • I continued exploring novel strategies to exploit muon collisions. The paper published this year outlines a novel strategy to measure the Higgs to invisible decay that is uniquely enabled by muons.
-I was invited to give seminars and talks at conferences, including:
  • "Higgs 2023" conference. Closing talk "Physics perspectives for future colliders and overall outlook". IHEP, Beijing, China.
  • "Higgs Hunting 2023". Talk "Questions on Higgs physics". Orsay-Paris, France.
  • I gave a Colloquium "Why building a muon collider" at LPSC, Grenoble, France.
-I contributed to LHC physic by:
  • Organising the workshop "The LHC Precision Program" at the Centro de ciencias de Benasque Pedro Pascual
  • Acting as convener of the "PhysTeV 2023" Les Houches workshop.
-In May, my former PhD student defended her thesis "Searching for Unexpected New Physics at the LHC with Machine Learning" at the University of Padova and CERN. She was awarded by an IAIFI postdoctoral fellowship at MIT.
In September, my new PhD student Francesco joined IFAE.
