Irène Bacle spent most of her career in the pharmaceutical industry where she developed a strong expertise of all areas of sensory evaluation. She has applied sensory analysis to many consumer good categories, including cosmetics, personal care products, oral and dental care, as well as to drugs and medical devices. She has experienced cultural diversity while working with panels in many different countries in Europe, Asia and South America. This led her to value the importance of product usage and specific consumption habits in all her projects. She is now a consultant in sensory analysis and works with companies to assess their needs and to design and set up efficient sensory and consumer studies.
