Chemistry training across continents
Shem Oyoo Wandiga was born on 22 September 1939. The Kenya National Academy of Sciences locates his early life in Karachuonyo and records schooling at Kamagambo and Pine Forge Institute in Pennsylvania. He studied chemistry at Howard University, earned a master’s degree at the University of Maryland and completed a doctorate at Case Western Reserve University in 1972.
He returned to Kenya and joined the University of Nairobi’s chemistry department that year. His academic career included teaching, research and departmental leadership. Coordination and analytical chemistry supplied a laboratory foundation for later work on environmental questions.
Following chemicals through the environment
Wandiga investigated environmental contamination as well as chemical structures. The academy’s profile highlights trace-metal studies involving hair, fish, water and sediments. These different specimen types connected analytical chemistry with questions about how substances move through biological and environmental settings.
An international collaboration took him into atmospheric science. With Patrick Zimmerman, James Greenberg and Paul Crutzen, he coauthored a 1982 Science paper about gases emitted by termites. Its abstract presented possible global emissions calculated from laboratory measurements, with field checks at two nests in Guatemala. The scale of that estimate depended on extrapolation; it was not a direct count of emissions everywhere.
Climate research needed several disciplines
The same concern with connected environmental processes appears in a 2010 study of epidemic-malaria vulnerability in East African highlands. Wandiga worked with a large team including Maggie Opondo, Daniel Olago and Andrew Githeko. The author-repository abstract connects climate and hydrology with health records and household circumstances.
The coauthors considered coping and adaptive capacity alongside physical exposure. Linking climate, hydrology, health records and household circumstances required cooperation across specialisms. The project illustrates why a chemist’s research network could involve geology, meteorology, public health and social science.
Institutions carried the work forward
Wandiga’s responsibilities extended beyond individual papers. KNAS lists him as chairman for 1992–2002. At Nairobi he held senior academic and administrative roles and helped establish the Institute for Climate Change and Adaptation. These institutions provided settings in which researchers could teach, collaborate and develop further projects.
The Royal Society of Chemistry’s obituary also records his contribution to the Pan Africa Chemistry Network and his service in university governance. It dates his death to 18 May 2026. His legacy lies in identifiable research collaborations and institutions, as well as the students and scientific communities that continued their work.
Quick answers
Frequently asked questions about Shem Wandiga
- Who collaborated with Shem Wandiga on the 1982 termite paper?
- The listed authors are P. R. Zimmerman, J. P. Greenberg, S. O. Wandiga and P. J. Crutzen.
- Did that paper directly measure a worldwide termite total?
- Its abstract describes a global estimate calculated from laboratory measurements, with field checks at two nests. Extrapolated estimates and direct global measurement are different kinds of evidence.
