I am a biologist who trained at the Universities of London and of Nairobi.
Most of my research and teaching I did at both a government veterinary research laboratory and in a veterinary school. I have also worked in the commercial sector: as a copy-editor of scientific textbooks, and as a survey biologist for an industrial scale pest control company.
My research speciality is infectious and parasitic diseases of domestic animals, with particular emphasis on the insect, mite and tick transmitters of pathogenic microbes. (Go to http://www.researchgate.net/profile/Alan_Walker7 for a list of publications and their downloadable files.) Mostly I worked on diseases of livestock in the tropics. This was done in Kenya for a decade. Then followed collaborations and consultancies in fourteen other tropical and sub-tropical countries from South America to India, and laboratory work in Britain at the veterinary school in Edinburgh. Currently I am affiliated to the College of Medicine and Veterinary Medicine of the University of Edinburgh, through which I provide editorial and consulting services. This experience inspired the writing and illustration of guidebooks to insect, mite and tick parasites of domestic animals featured here.
My writing now is for the popular science market, aimed at a wide audience. I ask questions and provide some answers about the complex and counter-intuitive relationships between technology and fundamental research.
My wife and I live in Scotland. Our children have left home but now we help them raise their children. To relax we go into the mountains of Britain and the French Alps hunting for flowers with a camera.
