Present

However, my main line of work nowadays, is in assisting coffee projects in underdeveloped areas. As a one man band I can work in those areas that larger consulting companies are not interested in, or are just too expensive.

I have now semi-retired, back to my home in the south of New Zealand where I am still working in Soil Microbiology, Dairy Waste Water Treatment Systems, and Earthworms. See my publications for the various sectors of my experience and expertise.



Previous experience

During the 1990s I completed a 10 year term at the Papua New Guinea Coffee Research Institute, as Prin.Res.Scientist for Coffee Processing. (Ref.) For details of the PNG CIC CRI, see www.coffeecorp.org.pg and their email address is: cofres@datec.net.pg

Since then I have worked on projects in Tanzania, Vietnam, Honduras, New Caledonia, India.  See, GTZ Vietnam Coffee, that of course is just part of the bigger picture, Vietnam Coffee and Cocoa Association for details.

From 1983-1989 I was also engaged by the Commonwealth Secretariat to work on regeneration of Pacific Coral Atolls. To see this, look at the bottom of my Publications page.
