Catherine was one of the pioneers of French radio astronomy. She began by studying solar radio emissions. Then, during her 3rd cycle thesis, she carried out a theoretical study of particle acceleration and turbulent heating of Alfven waves in radio galaxies (her 1977 paper on the subject is still highly cited). She then had the good fortune, as she herself put it, to take part in the space adventure with Jean-Louis Steinberg and his group. She was able to use the first measurements of radio emissions from instruments onboard the ISEE-1,2,3, Wind and Cluster space missions. Throughout her career, Catherine has been able to study in detail the physics of the Earth’s shock, in particular, reflected emissions from the upstream shock front and downstream turbulence in the so-called ’magnetosheath’ region, and turbulence in the free solar wind. One of the latter results obtained with the Cluster mission and published in 2014, on the statistics of ’whistler’ waves in the solar wind, is a basic reference for current studies with Parker Solar Probe and Solar Orbiter.
Catherine’s latest publication (in 2020), based on the statistics of turbulent spectra at kinetic scales in the solar wind, is in collaboration with an international team of theorists in natural plasma physics. She retires in 2022.
