Mission

I am in charge of the research experimental activities at LRS, including the CROCUS experimental reactor and the LOTUS cavity. I am Deputy of the Head of the nuclear facilities Oskari Pakari, for supporting him in the management of the LRS controlled area in the PH building. Finally, I am contributing to the LRS teaching activities, for the management of the EPFL-ETH Zurich joint program in Nuclear engineering, with the Radiation detection lecture, and especially for the TP and Radiation and reactor experiments at our facilities.

I am one of the four Scientific staff members at the School Assembly, Basic Sciences Faculty Council, and Institute of Physics Council for the current mandate.

Biography

After a PhD on the measurement of (p,n) reactions cross sections on small accelerators (IRSN, France), I have worked on the development of neutron detectors and measurement methods for reactor physics (CEA, France). I am part of the LRS staff since October 2014. I have a double affiliation with the Paul Scherrer Institute since 2016, where I defended my tenure in 2020.

Research

My research activities consist in the experimental research work of LRS, detailed on its website: here.

My current work consists in analysing the PETALE experiments on stainless steel nuclear data, and preparing the next programmes in the CROCUS reactor on intrapin flux measurements (NECTAR), and sample oscillation (BLOOM). I am also co-directing one PhD thesis on the analysis and extension of PETALE within the HARVEST-X project.

Two of my PhD students, Fanny Vitullo and Yifeng Jiang (co-direction in collaboration with CEA, France), recently defended their theses on the development of in-core neutron measurements with miniature scintillators, and on neutron modulation in nuclear reactors, respectively.

Courses

Radiation and reactor experiments

The reactor experiments course aims to introduce the students to radiation detection techniques and nuclear reactor experiments. The core of the course is the unique opportunity to conduct reactor experiments, as the control rod calibration, and approach to critical.

Radiation detection

The course presents the detection of ionizing radiation in the keV and MeV energy ranges. Physical processes of radiation/matter interaction are introduced. All steps of detection are covered, as well as detectors, instrumentations and measurements methods commonly used in the nuclear field.
