Dominique Lancastre was born in Guadeloupe. After obtaining his baccalaureate, he left Guadeloupe to study at Paris XII University, where he was awarded a Bachelor of Arts and a Master of Arts. He pursued his studies further in American Studies. His work, over that period of studies, was focused mainly around aspects of inequalities in schools and education in the United States, particularly during the 1960s.

He was a teacher for several schools and lycées in the Académie Paris Versailles Créteil. He is currently employed for British Airways. During this period working for British Airways and flying around the world, he became aware of the importance of his Creole culture and decided to write about it and to promote it. He published La Véranda (Éditions Beaurepaire, 2010) for which he won the Bal de Paris Award for Overseas Books in 2011. Une Femme chambardée (Éditions Edilivre, 2012) is his second novel.
