About me

I am a postodoctoral researcher currently working in the Guenette group on MicroBooNE and DUNE, two accelerator-based neutrino experiments using liquid-argon time projection chambers. Previously, I was doing research in the collider experiment ATLAS, as part of which I completed my Ph.D. at McGill University. 

Current work

Charged current interaction of muon neutrinoMiniBooNE observed an unexpected excess of events at low energies, O(100 MeV), compatible with the production of electrons in charged current interactions of electron neutrinos. MicroBooNE is located near MiniBooNE to have access to the same accelerator-based neutrino source such as to be able to understand this excess. I am using charged current interactions of muon neutrinos to constrain the uncertainties in the observation of such events.

 

Testing benchA critical component of liquid-argon time projection chambers are the anode plane assemblies, the wire planes. DUNE will consist of an unprecedented large number of these assemblies. To ensure that their construction quality is sufficient for the successful operation of DUNE, the tension of each wire is to be measured. To decrease significantly the time needed for such a task, as hundreds of thousands of wires need to be measured, I am designing, building and testing a tension measurement device based on a novel electrical wire-tension method.

Previous Work

Photon and heavy quark productionI measured differential cross sections of the associated production of a photon and a heavy quark in proton–proton collisions with the ATLAS detector. The heavy quark, either a b or c quark, is observed as a particle jet. It is the first measurement of these interaction processes. The measurement leverages the excellent experimental precision of photons to probe the heavy quark content of the proton. This type of measurement helps in understanding better the composition of the proton and can be used to constrain modeling uncertainties.

Jet

 

I also contributed substantially to the ATLAS trigger system. More specifically, I programmed, validated, operated and monitored the trigger subsystem dedicated to particle jets on a day-to-day basis. In particular, my work ensured that this subsystem would be performing as expected at the restart of the experiment after its first long shutdown, along the rest of the trigger system.
