Dr Usha Krishnan is a Senior Lecturer with the School of Women's & Children's Health. She is also the director of the only paediatric motility service and dedicated multidisciplinary oesophageal atresia-tracheoesophageal fistula clinic in the state. Her research interests lies in childhood motility disorders, functional gastrointestinal disorders, gastroesophageal reflux disease and reflux aspiration, growth and nutrition, eosinophilic esophagitis, gut microbiome and oesophageal atresia.
