Entomology, (integrated pest management, especially for Lepidoptera and Orthoptera); terrestrial and aquatic biology. Environmental monitoring (biodiversity); Project monitoring, Project evaluation; Field survey, training and operational logistics.
Key expertise and experience:
Entomologist, (tropical and temperate). Oil palm entomology, IPM of oil palm pests.
Biodiversity monitoring of Non-target Organisms (NTO’s), aquatic (FW) habitat inventories.
Locust Ecologist (survey & control), with regional logistical and technical responsibilities to Locust Control Sections (in Sudan and Eritrea).
International consultancy and operational research experience in Amirantes Islands, Botswana, Burundi, Cyprus, Djibouti, Eritrea, Ethiopia, Gambia, Georgia-CIS, Ghana, Guinea-Bissau, Israel, Kazakhstan, Kenya, Madagascar, Malawi, Morocco, Papua New Guinea, Rwanda, South Africa, Somalia, Spain, France, Sudan, Tanzania, Uganda, Yemen Arab Republic, Zambia, and Zimbabwe (29 countries, 19 in Africa).
Fifteen years of operational and management experience including all aspects of field operations with, Desert Locust Control Organization for eastern Africa, responsible to the Director and member country governments (up to and including Ministerial level) which included, Kenya, Tanzania, Uganda, Ethiopia, Djibouti, Somalia, Sudan, & Eritrea. Latterly as project manager overseeing multidisciplinary and multi-cultural projects for the management of an applied, regional programme for migrant pest management, in African agricultural and rangeland systems, and which consisted of a large multi-disciplinary, multi-ethnic team of resident and visiting research and development scientists from a wide range of biological and physical disciplines.

I am currently Head of Entomology for the PNG Oil Palm Research Association, providing technical advice to the palm oil producing industry and smallholder growers on all pest related issues for oil palm in Papua New Guinea, with special emphasis on IPM methodologies within the framework of ISO 14001 and RSPO.
Previously I was a freelance biological specialist Consultant, and a founder Member of theNRgroup of Development Professionals (www.thenrgroup.net), where I was involved in a number of projects, e.g., environmental monitoring of the effects on biodiversity and health, of locust control operations in Kazakhstan, biodiversity monitoring survey of a reclaimed gravel excavation site, saline habitat surveys, and bat habitat surveys for the building industry in the United Kingdom.
In March 2004, I returned from an overseas posting at the Plant Protection Department, Ministry of Agriculture, Sudan with the FAO EMPRES programme for the control of Desert Locust. This involved logistical, technical and training duties with extensive fieldwork. The majority of my working life has been spent overseas, primarily in Africa where I was involved in a multi-disciplinary, multi-ethnic project on the ecology, management and control of the African armyworm, a migratory noctuid moth pest of cereal crops. My work there required that I travel extensively throughout the region, providing training, operational advice, research and representation at meetings. Latterly I was the Project Manager.
At NRI, I was an integral part of many small projects involved mainly with ecotoxicology, and preparation of Handbooks for reference and training. I worked on project evaluation in Georgia-CIS on Colorado beetle.
I have undertaken work monitoring freshwater biodiversity in UK, and will be involved in aquatic invertebrate monitoring for environmental assessment in Papua New Guinea.
I have undertaken both short-term and longer-term consultancies, mainly involving locusts and armyworm, also in Africa.
I have worked in 29 countries, 19 of which were in Africa.
I am currently working in West New Britain, Papua New Guinea.
