Early life and education
Catherine MacGregor was born Catherine Fiamma in Morocco. Her parents, both mathematics teachers with Corsican and Basque roots, raised her in Casablanca until she was 14. She attended Lycée Lyautey there, and later moved to Paris with her mother. She pursued higher studies in the field of energy and engineering, earning a bachelor’s degree in engineering from École Centrale Paris in 1995.

Career
She joined Schlumberger in 1995 and remained for 23 years. Her roles included being the group's HR director. From 2013 to 2016, she led operations in Europe & Africa. In 2017, she became the President of drilling activities in London. She was keen on using 3D seismic technology for enhanced oil recovery while at Schlumberger.

In 2020, she became the President of Technip Energies (based in Paris), a spin-off from TechnipFMC. Her tenure saw a focus being provided on energy transition.

The board of the French energy company Engie named her as the next CEO on 2 October 2020, and she assumed the position on 1 January 2021. During that period, as her predecessor Isabelle Kocher, she held the distinction of being the sole female CEO in France's CAC-40 stock index until Christel Heydemann joined as the CEO of Orange S.A.. The French Finance Minister, Bruno Le Maire, described it as 'regrettable' that more women were not in similar positions alongside her.
