I am involved in the following research direction:

Simulation of events with QCD radiation

The aim of this project is to quantify the impact of using jet matching techniques in the context of the production of multi-jets processes, in the Standard Model and beyond. Such methods mix the PS simulation and the matrix-element calculation, leading notably to a strong reduction of the sensitivity to parton shower parameterization.
