Fabienne Keller is an engineer and graduate of the Ecole Polytechnique, the Ecole Nationale du Génie Rural, des Eaux et des Forêts and the University of Berkeley. She began her professional career at the Ministry of Agriculture and then at the Ministry of Finance, before moving to the private sector and joining the Crédit Industriel d'Alsace et Lorraine. Her political involvement began in the Neudorf district of Strasbourg, where she was elected as a departmental councillor, then as a regional councillor. She was the first woman to sit on the Bas-Rhin General Council. In 2001, she was elected Mayor of Strasbourg and Senator of the Bas-Rhin in 2005.

Passionate about transport and mobility issues, in 2009 she authored a report on 'the contemporary railway station' which led to the creation of the subsidiary SNCF Gares et Connexions. She was also a director of Réseaux Ferrés de France (RFF) between 2009 and 2019, rapporteur for transport in the Senate between 2014 and 2019.
