Of the world's roughly 7,000 languages, fewer than 100 are well served by current AI systems. Nigeria alone has over 500 — with Igbo, Hausa, and Yoruba spoken by a combined 150 million people. Dr Ezeani's research treats language technology as infrastructure, and starts from the conviction that its absence falls hardest on those already at the margins.
Over more than a decade at Lancaster University — extended through Microsoft Research Lab Africa — his work has spanned African language NLP, minority-language tools for Welsh in active government use, digital and spatial humanities, and real-world AI deployment at population scale. The unifying methodological commitment: NLP can be made to work rigorously and equitably in any linguistic or cultural context, provided researchers build the infrastructure from the ground up.
He holds a PhD in NLP (Sheffield, 2019), a 2024 CoSeC Fellowship from UKRI-STFC, and an OpenAI Researcher Access Grant, and serves as Associate Editor of ACM Transactions on Asian and Low-Resource Language Information Processing. He is a long-standing contributor to the Masakhane community and served on the Technical Advisory Panel of the Lacuna Fund's African language dataset grants.
