I give scientific advice to many firms of engineers and architects on historical engineering practices and undertake commissions analysing traditional building materials particularly where their decay impairs structural performance.

I have been a consultant with Arup since 1982 and have considerable international experience with the assessment and conservation of masonry buildings, sites and landscapes in the Middle East and Asia - especially World Heritage Sites.

I am a senior historic Building Conservator and Specialist Archaeologist to many international and national agencies including UNESCO, UNDP, Aga Khan Cultural Services, World Bank, Asian Development Bank, and Egypt Exploration Society.

I am most pleased with my conservation projects on internationally important historic buildings in the Himalayas. Here it is all ‘hands-on’ problem solving. One wonderful aspect of this has been the community based conservation approach with its development and better health objectives. Now we are into training the second generation of young architects, engineers and crafts persons.

I am a Fellow of the Royal Geographical Society and of the Society of Antiquaries of London.
