Alice PISANI, PhD "Light on the dark side of the universe"

Let's discover the portrait of Alice Pisani and the video of her performance during the 2016 L'Oréal-Unesco For Women In Science fellowships in France.

The stars, the galaxies… we are drawn to look at things that shine. And yet, a key to understanding the expansion of the universe may well come from the study of cosmic voids, regions where there are very few galaxies. This is the original subject of Alice Pisani’s post-doctoral research at the Centre de Physique des Particules de Marseille. The study of these cosmic voids has been neglected until recently. However, analysing the properties of cosmic voids could contribute not only to measuring the universe’s expansion, but also discovering more about the nature of black energy, which makes up 70% of the universe. 

For her doctorate, Alice Pisani developed a method enabling the detailed reconstruction, for the first time, of the shapes of cosmic voids, based on telescopic data. She has also proven that counting cosmic voids allow you to measure the properties of dark energy. These new methods will now be applied to the observation of hundreds of thousands of additional galaxies. She loves sharing her passion for science with young people, wanting to inspire them. “I took on the challenge of a career in science, driven by the desire to understand that which is infinitely big. I found it inspiring that it was possible, using mathematical equations, to describe the universe in its totality”, the young researcher explained.
