He has consulted on kimberlite projects in Southern Africa and undertaken the assessment of kimberlitic rocks in Russia, Brazil, Canada, West Africa and South America.

Paul also owns and manages a kimberlite indicator mineral picking laboratory and consults and advises widely on kimberlite petrography and mineral chemistry as predictors of diamond carrying capacity.

Paul has co-authored several academic papers, the principal ones being:
