Professor Gideon Lack is a world-leading paediatric allergist and the founder of London’s LACK Allergy Clinic. His groundbreaking research has transformed how food allergies are prevented and treated worldwide. As Principal Investigator of the landmark LEAP (Learning Early About Peanut allergy) and EAT (Enquiring About Tolerance) studies, he overturned decades of medical advice and helped prevent thousands of cases of food allergy in children across the globe.

Professor Lack studied medicine at Lincoln College, Oxford, before training as a paediatrician in New York and specialising in Paediatric Allergy and Immunology in Denver, Colorado. In 1995, he returned to London as a Consultant at St Mary’s Hospital, where he led the Department of Paediatric Allergy and Immunology for 12 years. He became Professor of Paediatric Allergy and Immunology at Imperial College London in 2005, and joined King’s College London the following year, where he continues to teach and conduct research.

Today, Professor Lack heads the Children’s Allergy Service at Evelina London Children’s Hospital and leads the LACK Clinic in central London, providing specialist care for both children and adults.

His contributions have been recognised with numerous awards, including the William Frankland Award for Outstanding Contribution to Allergy from the British Society of Allergy and Clinical Immunology. He serves as a Consultant to the Sean Parker Allergy Centre at Stanford University, sits on the Editorial Boards of The Journal of Allergy and Clinical Immunology and Clinical and Experimental Allergy, and is Secretary to the Food Allergy Section of the World Allergy Organisation.

Professor Lack’s expertise spans the full spectrum of allergic disease, from severe childhood asthma and anaphylaxis to food allergies, eczema, hay fever and immunotherapy. His ongoing research continues to pioneer new ways to prevent and treat allergic conditions, building on the paradigm-shifting insights of the LEAP and EAT studies.
