Research interests

Linda at XMASS

Here is a picture of me while visiting the X-MASS experiment at the Kamioka mine (Gifu prefecture, Japan). That is not of course how I dress every day at work.

My research interest is mainly focused on neutrino physics and friends. By friends I mean particles produced in neutrino interactions (such as pions) or particles that could lead to the production of neutrinos, such as cosmic rays. I like to divide the areas I work/worked with in 3 categories:

In this page you can find the main focuses of my research in the past few years (non in chronological order). The right bar will help you navigating through the content.

Ultra high energy neutrinos


Since June 2015 I am a Research Associate at UCL and I'm part of a team of ultra high energy neutrino hunters. Neutrinos can travel very long distances undisturbed and ultra high energy neutrinos (>10^{18}eV) offer a unique insight into astrophysical phenomena outside our galaxy.

At UCL we are involved in two experiments in Antarctica which use the Askaryan Effect to detect ultra high energy neutrinos. The ANITA experiment (photo on the left) uses radio antennas attacched to a balloon that periodically flies over the Antarctic ice to detect neutrinos. I spent about 5 weeks in Antarctica in December 2016 to build, calibrate and launch ANITA-4. Check out the photos from my trip on Flickr showing the science and life at McMurdo Station. A summary of the latest flight can also be found here).

Using as well the Askarian Effect, the ARA experiment employes antennas buried 200 m in the Antarctic ice to look for neutrinos. Currently there are 3 operational stations at the South Pole and we are hoping to add more in the next years.

Long baseline neutrino experiments

During my PhD at Queen Mary University of London, I worked on the T2K long baseline neutrino experiment. The main goal of T2K is the measurement of neutrino oscillation parameters.

As oscillation experiments gather more statistics, they are starting to get limited by systematic uncertainties. Some of the largest systematics come from the modelling of neutrino interactions. Thus, the main focus of my T2K analysis was the selection and cross-section measurement of muon neutrino scattering with nucleon resonant excitation and production of a single charged pion in the water layers of the T2K near detector, ND280.

Looking at the future of neutrino oscillation experiments, I evaluated the physics potentials of a future long-baseline experiment between J-PARC and Hyper-Kamiokande to precisely measure the neutrino oscillation parameters and potentially discover CP violation in the lepton sector.

Cosmic ray muon tomography

Current techniques to inspect large volumes (cargos, ships) use X ray which has 2 bad points: it's harmful and everything denser than concrete cannot be distinguished. The scintillation technology used in neutrino experiments can be used to detect cosmic rays and their path before and after transversing a volume. Cosmic rays are harmless and can inspect high density volumes. The only down point of this technique is the low flux of cosmic ray. As part of my Master project at UCL I improved the reconstruction technique of the CREAM TEA experiment which aims to use cosmic rays to inspect large volumes with harmless radiation.
