I previously worked for the Natural Resources Institute (NRI) in the UK on projects in Africa and Asia, before joining ILRI in 1999. My research interests evolved from an early focus on livestock nutrition and production into a more general approach to feed resource utilisation and farming systems. During the past few years my research interests have focused on understanding how knowledge is generated, spread and utilised. I played a key role in developing ILRI commitment to using innovation systems perspectives to increase the effectiveness and impact of research. At CABI  my remit is to oversee all projects within the knowledge for development theme.
