Lloyd Markham was born in Johannesburg, South Africa, moving to and settling in Bridgend, south Wales when he was thirteen. He spent the rest of his teenage years miserable and strange and having bad nights out before undertaking a BA in Writing at Glamorgan followed by an MPhil. He enjoys noise music, Japanese animation and the documentaries of Adam Curtis. He operates synthesisers in a band called Deep Hum and has less bad nights out these days.
His first novel, Bad Ideas \ Chemicals (Parthian, 2017), was chosen for the 2017 Literature Exchange Bookcase. Lloyd attended the launch of the Arabic translation of his novel in Cairo Book Fair in Janurary 2020.
