Nancy Peña, born in Toulouse in 1979, got her interest in comics through her father, a comics collector.
She made her first comic online with Vincent Rioult, called 'Les Carpates'.
She studied applied arts, and became an art teacher herself later on. Her first comics were printed in such collections as Grain de Sable ('Le Péril Léporide') and at the publishing house Boîte a Bulles (her long story 'Le Cabinet Chinois').
She has also published in the magazine Patate Douce.
