Paediatric gastroenterology captivates Dr Deb as it provides a balance between general paediatrics and specialised knowledge. It also allows her to perform practical procedures, including endoscopy, and to pursue her interest in academic research, which remains a driving passion.

Dr Deb's PhD thesis investigated the role of the microbiome in childhood Crohn's disease. She is deeply intrigued by the human microbiome and its connection to health and disease. One of her ambitions is to elucidate the role of gut bacteria in childhood inflammatory bowel disease and explore the potential of modulating the microbiota to achieve long-term disease-free remission in children with Crohn's disease and Ulcerative colitis.

Her dedication to advancing the field of paediatric gastroenterology and her commitment to improving patient outcomes through research make Dr Deb a valuable asset to The Portland Hospital.
