Meet Professor Lack

Lead Consultant

Professor Lack is a world-leading expert in allergy care who has transformed our understanding of how allergies develop and how we can prevent them. His groundbreaking LEAP study proved that early introduction of peanuts could reduce allergy risk by up to 85% - a discovery that has changed global health guidelines and has since protected many children from developing food allergies.

As Clinical Director at the LACK Clinic, and through his research at Imperial and King's College London, Professor Lack combines evidence-led knowledge with compassionate patient care.
