I am a fourth year DPhil student working on the ERC project 'Highest Precision QCD predictions for a new era in Higgs boson phenomenology' supervised by Prof. Fabrizio Caola. I am a member of the Mansfield College.

My research is focused on multi-loop scattering amplitudes in the Standard Model. They are key theoretical predictions for elementary particle phenomenology at the Large Hadron Collider. As an example, I computed the amplitude for diphoton production in gluon fusion at 3-loop QCD. We are using this result to put stringent constraint on lifetime of the Higgs boson. Moreover, I am computing the 2-loop mixed QCD-Electroweak amplitude for the Z+jet production at proton colliders.
