I am a veterinarian with a PhD in Epidemiology from the University of Nairobi. My early research was on smallholder pig health and production. My post- doctoral research was on traceability in cattle traded in major routes in East Africa. I taught at the Faculty of Veterinary Medicine, University of Nairobi, prior to joining ILRI. Currently, I work for ILRI as a scientist, based in Nairobi, Kenya. My research interests are on food safety and One Health.
