I am a professional Engineer with the Engineers board of Kenya, and a corporate Member of the Institution of Engineers of Kenya for which I chair the Agriculture subcommittee of the Policy Research and Advocacy committee. I am also a Senior Lecturer, and Chairman, Agricultural & Biosystems Engineering Department, Kenyatta University, Kenya. I have contributed to the formulation of Regulations under the Environmental Management Act, as well as sit on the Sanitation and Water treatment technical Committee of the Kenya Bureau of Standards. My Area of specialization is the Soil, Water, Environment (Ecological Engineering) option of Agricultural Engineering, with strong research interests in Pro-Poor Low-Cost Environmental Sanitation Technologies, Green Economy, smart agriculture, production of neglected food crops and Sustainable Diets Systems. I have been involved in novel elements of research on the appropriate technologies in the handling of wastewater, solid waste and environmental studies. I have also worked on the improvement of data sources used in the modeling of watersheds which are grossly deficient in data (a typical problem in most countries in Africa), by using satellite imagery and integrating them into a model for simulation production.
