Profile Introduction

Neural innervation of the gastrointestinal tract, in particular the primary afferent innervation.

Degrees

1986 PhD Physiology University of Liverpool, United Kingdom
1977 BS Biological Sciences University of Birmingham, United Kingdom

Research Interests

Neural innervation of the gastrointestinal tract

Vagal afferent neurons, including their role in GI physiology and food intake.  Research is also looking at how the phenotype of these neurons change in obesity and metabolic disease.

Gut Microbiota

Influence of gut microbiota on GI physiology, including gut epithelium and intestinal barrier function and on plasticity in vagal afferent neurons
