[1] In his thesis, Unicité de la supergravité D=4 N=1 par les méthodes BRST,[citation needed] he demonstrated the uniqueness of N=1 supergravity in four spacetime dimensions with minimal assumptions using homological methods.

This was a major result in the field as it showed that under mild assumptions that if a free graviton is coupled to a particle of spin 3/2, the only consistent theory will have supersymmetry.

He joined KU Leuven as a Marie Curie Fellow, working with Antoine Van Proeyen and Frederic Denef on string theory and supergravity.

He moved to the Department of Mathematics in 2013, and was appointed Benjamin Peirce Fellow working with the Fields Medal winner Shing-Tung Yau.

[8] In 2022, Esole was listed as one of the ten members of the newly created African Advisory Board of the French National Center for Scientific Research (CNRS).

To achieve this, we have surrounded ourselves with personalities with whom we can take the right measure of the field, who will help us question our practices and usefully mobilize our forces".

[16] In July 2022, Esole became a nonresident senior fellow of Atlantic Council's Africa Center, directed by Ambassador Rama Yade.
