Document Sample


I am professor of Chemistry at the Maseno University teaching both Undergraduate and Postgraduate students in Organic and
Analytical Chemistry.

I do research in natural products Chemistry. Currently my major interests are in the analysis of chemical pollutants, biologically
active compounds found in herbal and commercial plants in Kenya as well as synthesis of useful organic or organmetallic
compounds. The laboratories at Maseno University and ICIPE in Nairobi and the departments of mines and geology of the ministry
of Natural Resources enable me to analyse both inorganic and organic pollutants arising from industries and agricultural effluents.

I have done consultancy for Pyrethrum Board of Kenya, Sugar Industries, Kisumu Municipality and Research for Kenya Marine
Research Institute on environmental problems. The problems cover pesticides, petroleum products, heavy metals and water quality
in the effluents.
