Joey DeCourcey PhD

Senior Scientific Officer

Joey DeCourcey PhD is the Senior Scientific Officer at Allergy Standards Ltd. Dr. DeCourcey is responsible for the development of new scientific standards at ASL and ensuring that new and existing standards are in line with the most current international testing standards.

Joey holds a BSc in Analytical Science and a PhD in Immunology. He has over 10 years’ experience working in molecular, clinical and industry led research in Ireland and the UK. Joey has an in-depth knowledge of inflammatory disease mechanisms, assay development and analytical techniques. He has led several industry-partnered research projects focussing on novel anti-inflammatory functional food ingredients with partners such as Kerry Foods and Mead Johnson Nutrition, including a project focussed on the development of novel infant formula ingredients suitable for infants with Cow’s Milk Protein Allergy (CMPA). After working in the UK in The Department of Experimental Medicine and Rheumatology at Queen Mary University of London, he returned to Ireland and completed a 3-year project at Trinity College Dublin focussing on the development and commercialisation of novel anti-inflammatory compounds for use in treating auto-immune diseases. He joined Allergy Standards in 2018 as Senior Scientific Officer.

Dr. DeCourcey has presented the results of his work at several international conferences including the International Keystone symposia, the European EULAR congress, the British Society for Immunology congress and the Irish Society for Immunology congress. His work has been published in international peer-reviewed journals such as Nature Communications and Frontiers in Immunology.

Dr. DeCourcey leads the R&D program at allergy standards and represents the company at international conferences. He liaises with lab partners to ensure that testing is carried out according to the rigorous standards developed at allergy standards for the asthma & allergy friendly® Certification Program and is the point of contact for technical and R&D staff for prospective and client companies.
