She is a former commercial airline pilot-instructor and holds a Master's degree in theoretical physics and astronomy. She served as the Commander of a Mars simulation in Utah and participated in the ESA astronaut selections in 2008.

An international motivational speaker and guest lecturer, Nancy has presented at numerous prestigious platforms, including TEDx events, Deloitte University, and the European Commission. She is also the author of "Iedereen Ruimtevaarder" (Everyone an Astronaut, 2021) and "Aerospace Attitudes – Word piloot van je eigen leven" (2025), where she translates valuable aerospace insights into practical lessons on leadership, teamwork, and communication.
