Previously head of children’s allergy services at Evelina London Children’s Hospital between 2015 and 2023, Professor Helen Brough is a consultant in paediatric allergy and clinical immunology.

Having trained in some of the UK’s leading teaching hospitals including Guy’s and St Thomas’ Hospitals, King’s College London, and Great Ormond Street – Professor Brough hold dual accreditation and is on the specialist register for both general paediatrics and paediatric allergy.

As a parent herself, Helen knows how distressing and concerned a parent can be when dealing with their child’s condition. Her practice is child-centred and she believes in always giving parents and their child the time needed to fully discuss all concerns, guiding and supporting you both through treatment plans.


After graduating from King’s College, Cambridge University, with double honours in medicine and experimental psychology Helen went on to complete her clinic training at the Royal Free and University College London Medical School.

She trained in paediatrics at South London Paediatric rotation and was awarded one of the few recognised higher specialist training posts in paediatric allergy and immunology – the MADEL clinical lecturer.

Professor Brough completed an MSc in Allergy, gaining a distinction at the University of Southampton. She was awarded a PhD in determining routes of developing peanut allergy at King’s College London University.


Professor Helen Brough is actively involved in research to prevent, diagnose and treat food allergy. A professor at King’s College London and a Medical Advisor for the Natasha Allergy Research Foundation (NARF) she regularly lectures at national and international seminars and conventions.

Having co-authored several landmark studies on the prevention of food allergy, including the LEAP (Learning Early About Peanut) study, Helen was the lead investigator for the Pronuts study (assessing peanut, sesame and tree nut allergy), the Stopping Eczema and Allergy (SEAL) study, and an investigator for the oral and patch peanut desensitisation trials at Evelina London.

Professor Brough set up community children’s allergy services, and an allergy transition service for teenagers, to empower them to better manage their allergies.
She was awarded the 2020 Distinguished Clinician Award by the American Academy of Allergy, Asthma and Immunology, the Barry Kay award for excellence in Paediatric Allergy research from the British Society for Allergy and Clinical Immunology in 2013, and was awarded ‘Health Professional of the Year’ runner-up in 2010 by Coeliac UK.
