Valeria Pettorino is an Italian physicist working in cosmology, astrophysics and data analysis. She is a CDI Researcher at CosmoStat, CEA Saclay,[1] and she is part of Planck and Euclid ESA/NASA international space missions.

Her work is related to the use of data from ground and space missions to test theoretical models that describe the evolution and content of the Universe. Her work aims to describe the nature of dark matter and dark energy.

Career[edit]

Pettorino studied physics as an undergraduate and obtained her PhD from the University of Naples in 2005, with a dissertation "Dark energy in generalized theories of gravity".[2] In 2007 she joined the Euclid space mission and she became a Alexander von Humboldt Fellow at the University of Heidelberg. In 2009 she joined the Planck space mission and became Associate Research Fellow at Columbia University. She completed her PostDoc at SISSA in Trieste.

She works as astrophysicist and research engineer at CEA Paris-Saclay. Pettorino helped complete the final analysis of data from the European Space Agency’s Planck space telescope, which mapped the early universe with unprecedented precision.[3]

Pettorino is also on the leadership team for the Worldwide Mentorship Program for Women in Physics.[4] She also helped organize the annual EuroPython conference for users of the Python programming language.

Personal[edit]

Pettorino's uncle was physicist Roberto Pettorino (1946-2013), who worked in string theory.[2][5]
