She is best known for her weekly newspaper column under the pen name Ndèye Takhawalou and her Prix Emmanuel Roblès-winning 2004 novel La nuit est tombée sur Dakar, published under the pseudonym Aminata Zaaria.
"[2][4][5] After working for Sud Quotidien, Dièye began writing a weekly column in L'Observateur [fr], Senegal's most-read daily newspaper, under the pen name Ndèye Takhawalou.
[4] Dièye also began to write short fiction, and her stories were included in the anthologies Jeunes poètes du Sahel and Saison d’amour et de colère.
[3] The novel tells the story of two girls from Dièye's own home region of Thiès, who flee to Dakar in an attempt to avoid becoming an old man's second or third wife.
La nuit est tombée sur Dakar, like much of Dièye's work, is written in a simple, direct, yet emotionally moving style.
[1][3] Having trained at the National Academy of Dramatic Arts in Senegal, she occasionally performed as an actress, including in the short film La Petite Vendeuse de Soleil and in her own play Consulat Zénéral.
