Hi! I am a postdoctoral fellow in theoretical physics at the ETH Zürich.

Perturbative QCD

QCD

A lot of my current activity is devoted to making accurate theoretical predictions for processes in the Standard Model and beyond. I am currently developing a fully automated NNLO Monte Carlo simulator named MadNkLO with collaborators in Zurich, Switzerland and Debrecen, Hungary. Our goal is to implement a fully general extension of the Colorful method, but also to have a tool general enough to allow other many schemes to be used.

ML for integration

normalizing flow

Nearly all particle physics predictions are obtained by computing integrals, many of which are calculated numerically using Monte Carlo methods. Machine learning offers new avenues to optimize the integration process, which could significantly improve the success of methods like adaptive sampling beyond the capabilities of current approaches like VEGAS. I am currently exploring the idea of using normalizing flows to improve the convergence of Monte Carlo integrators and hope to make them part of our standard toolbox.

BSM Phenomenology

Despite the tremendous success of the Standard Model at particle colliders, we know that our theory for particle interactions is not complete yet, but we lack experimental evidence to complement it with new fields or interactions. The Standard Model EFT framework is an efficient and consistent way of encoding constraints and agnostically describe correlations between observables, and it is therefore a very desirable to have a large selection of observables predicted with precision and I am contributing to this global effort. I have also worked on Dark matter models based on extra-dimensional theories in the past.

Teaching & Outreach



As a postdoc at the ETH Zurich, I taught one exercise class and supervised five proseminar projects

  • 2017 - Electroweak theory, exercises (1 semester)

I was a TA at the University of Lyon, I have taught the following classes

  • 2016 - Introduction to QCD, exercises (1 semester)
  • 2015-2017 - Physics lab and exercises for 1st year biology students (3 semesters, electricy and optics)
  • 2016 - Physics exercises for 1st year physics students (1 semester, optics and mechanics)
  • 2016-2017 - Bibliography for 1st year students (3 semesters)
  • 2013 - Physics lab for 1st year chemistry students (1 semester, electricity and thermodynamics)



Introduction to extra dimensions at the undergraduate level: this is an proposal for how one could treat UEDs as an aside in an introduction to quantum mechanics, with an exercise designed to be a follow up to the "particle in a box".




Here is a video presentation on Threshold Expansions of loop integrals




I have participated to a science outreach program in French called "En direct du Labo" on Twitter.

My contribution has been storified.
