Ally Okeyo Mwai

ILRI Emeritus Fellow

Ally Okeyo Mwai was the Program Lead of ILRI’s Global Livestock Genetics- Live Gene Research Program. Okeyo is a quantitative geneticist with over 30 years of experience in practical design and implementation of livestock improvement programs in sub-Saharan Africa and South Asia regions. Okeyo has in the past led ILRI’s Breeding strategies Research, specifically focusing on development and implementation projects, covering a wide range of research areas including, characterization and genetic diversity of indigenous tropical livestock; their improved utilization, as well as development and application of assisted reproductive technologies in dairy cattle. Prior to joining ILRI, he was head of the Animal Breeding and Genetics Section at the Department of Animal Production, University of Nairobi and Coordinator of Small Ruminant Research Program at the then Kenya Agricultural and Livestock Research organization. Okeyo has and holds several national and international advisory board positions. He is currently leading the development of ILRI led dairy cattle genetic gain development and research programs in eastern Africa region. Okeyo has published extensively (authored and co-authored more than 150 scientific journal and conference papers), and has held several scientific editorials, and national and international advisory board positions. Okeyo holds MSc Animal Science (Animal Genetics) from University of California, Davis and a PhD in Animal Breeding and Genetics from University of Nairobi.
