Geoff Crockford started work as a human physiologist with a Medical Research Council unit based at the Dept of Human Anatomy, Oxford.  He then moved to the Dept of Occupational Health, London School of Hygiene and Tropical Medicine to run an MSc course in occupational hygiene.  Later he became head of the department's industrial service unit, and then the department. 

He learnt to dowse on a British Society of Dowsers course in 1995, and discovered that there appeared to be no adequate theory as to the physical basis of dowsing or the sensory system involved.  As a result he decided to see what was going on.  Observations and experiments soon led to the development of the Diamagnetic and Paramagnetic Theory of Biolocation upon which his dowsing work is now based.  Geoff's dowsing activities include water divining, archaeology (pre Roman), plant, tree and human auras, and dowsing services to industry.

Nigel Hughes is a London University science graduate.  Following completion of postgraduate studies in Scientific Research and Education, he worked in a number of scientific posts before embarking on a career in civil aviation as aircrew.  He flew as a jet captain for KLM as well as being a commercial flying instructor and flight examiner with over 10,000 flying hours.  After completing his flying career, Nigel worked in ICT, Business Training and Personal Development, becoming a consultant in leadership, motivation and personal development.  Currently he specialises in behaviour management, educational support and special education needs.

Nigel has been dowsing for five years and is a fellow research worker with Geoffrey Crockford, who developed the Paramagnetic and Dia-magnetic Theory of Dowsing, which successfully explains why dowsing works.  Based on rational and logical thinking, research shows it can be used as a powerful analytical tool, having many applications.

His dowsing research interests include pre-roman history and archaeology, health and wellbeing and natural earth energies, such as those associated with water, trees and the earth's atmosphere.  His goal is to enter dowsing research full time.
