The credentials of our academic authors are impressive, including Dr Tony Curtis on the business of the aroma trades, iconic pioneer David Williams and Past President of the British Society of Perfumers John Ayres on fragrance chemistry and application, John Wright internationally acclaimed authority on flavours and IFEAT Medal winner Dr Brian Lawrence on essential oils.
