Welcome to my homepage! I am a theoretical physicist studying quantum computing and elementary particles. I am an external collaborator with CERN and its Theory Department, after three years as a senior research fellow in this department.

My main research interests are higher-order QCD calculations (precision calculations) in Higgs and weak boson physics at hadron colliders, as well as recent and growing activities in quantum computing. I have also investigated neutrino mass models, supersymmetric theories, and effective field theories. I am also one of the developers of the codes NMSSMCALC and NMSSMCALCEW which are designed for the study of the Higgs boson masses and decays in the framework of the Next-to-Minimal Supersymmetric Standard Model (NMSSM), and the developer of the VBF Higgs pair production code in the VBFNLO collaboration. I have been contributing to the POWHEG-BOX and several of my programs can be found on the webpage of the POWHEG-BOX project. My latest computer program is n3loxs, which can calculate several cross sections at hadron collider at the current highest accuracy in QCD, namely next-to-next-to-next-to-leading order. The program is written in C++ and Python.

Before joining CERN, I spent five years from 2014 to 2019 as a senior postdoctoral researcher in the group of Prof.  Dr.   Barbara   Jäger at the Institut für Theoretische Physik (ITP) in the University of Tübingen (Germany) and three years at the ITP in the Karlsruher Institut für Technologie (Germany) as a postdoctoral researcher in the group of Prof.  Dr.   Margarete   Mühlleitner from 2011 to 2014. I got my PhD in France in 2011 at the Laboratoire de Physique Théorique in the University of Paris Sud (Orsay) under the supervision of Dr.   Abdelhak   Djouadi. Before my PhD I got my Master in theoretical physics at the École Normale Supérieure de Paris and spent my undergrad years at the École Normale Supérieure de Paris-Saclay which I entered after a very competitive exam which I passed, granting me a fellowship for four years as a civil servant.

On this website you will find mostly informations about my current work. One part of the website is dedicated to some miscellaneous, mostly in French, that I did up to my Master. By the way the picture you can see above was taken in the Russian Caucasus range in 2016 and is a view over the Elbrus twin summit. The west summit is 5642m high, making it the highest peak in Europe. After particle physics, hiking/alpinism is my second passion in life!

The study of the Higgs boson

After the discovery of a Higgs boson at the Large Hadron Collider (LHC) in 2012, particle physicists are now studying its properties. The biggest question today can be put simply as: have we found the (single) Higgs boson predicted by the Standard Model, or is it the first step into an entire new sector of physics?

This is what underlies my line of research on the Higgs boson.

Quantum computing

Machine learning and deep neural networks (DNN) are nowadays essential tools in many areas, from fundamental research to industry, logistic, finance, and so on. The networks become increasingly complex with many parameters. Is it possible to improve DNN using cutting-edge quantum-computing paradigm? Would it help reducing the energy consumption, thanks to a new different hardware technology?

These questions underlies my research in quantum machine learning.
