Dr Colin J Campbell

After being awarded a D Phil at Oxford in 1957, Dr Campbell joined the oil industry as an exploration geologist. His career took him to Borneo, Trinidad, Colombia, Australia, Papua New Guinea, the USA, Ecuador, United Kingdom, Ireland, and Norway.

He is now dedicated to researching the date and impact of the peak and decline of world oil production due to resource constraints, and to raising awareness of the serious consequences. He has published extensively, and his recent articles have stimulated lively debate. His views are provocative yet carry the weight of a wide international experience
