Hossein completed a PhD in Creative Writing at the J.M. Coetzee Centre for Creative Practice, University of Adelaide. His thesis, which explored the life and poetry of Forugh Farrokhzad, a pivotal figure in modern Iranian poetry, received the Dean’s Commendation for Doctoral Thesis Excellence in 2021.
His debut novel, Only Sound Remains, was shortlisted for both the Miles Franklin Literary Award 2024 and the Victorian Premier's Literary Awards 2024. This was followed by the 2025 publication of Desolation by Ultimo Press, which was highly commended at the Victorian Premier's Literary Awards in 2026. 
In his current role as a Research Fellow at Adelaide University, he leads the project, Writing the Self as Resistance in which the poetry of Forugh Farrokhzad provides fitting examples of writing as a sustained exploration of identity and resistance. The journal articles he has written under this project focus on the connection between the personal and the political, the role of writing in identity formation and artistic development, and the dynamics between life instincts and death instincts in Farrokhzad’s poetry.
In addition to academic and literary publications, his research has been disseminated through numerous public engagements. Since 2024, he has been invited to speak at major national events including Adelaide Writers’ Week, the Canberra Writers Festival, OzAsia Festival’s Weekend of Words, and the Australian Short Story Festival.
