I joined the University of Leeds as a Research Technician in November 2016 before taking the role as a Research Fellow in Gastrointestinal Disorders in 2017.

I obtained my PhD from the University of Hull in 2017 with one publication in International Journal of Oncology; Measuring the response of human head and neck squamous cell carcinoma to irradiation in a microfluidic model allowing customized therapy (Cheah et al., 2017; Int J Oncology 51, 1227-1238).

My current role as a Research Fellow is working with and in support of Professor's Houghton's research to ensure the completion of several projects. They are (1) Persistent bowel symptoms post-Clostridium difficile infection (CDI): Better definition of symptoms, insights into possible mechanisms and appropriate management; (2) Impaired pharyngo-esophageal motility and clearance of refluxate and/or swallowed boluses in respiratory disease and gastroesophageal reflux disease (GERD); and (3) Treating IBS with titrated ondansetron (TRITON): Barostat assessment of rectal sensitivity and compliance.

Research interests

1. Relationship between oesophageal motility (contractility) and reflux on patients (e.g. patients with Idiopathic Pulmonary Fibrosis IPF).

2. Effects of ondansetron on rectal sensitivity and compliance on patients with IBS-diarrhoea.

3. Post- infectious functional gastrointestinal disorders (FGIDs) following Clostridium Difficile Infection.
