Starch breakdown in the digestive tract

I completed my degree in Biomedicine at the University of East Anglia in 2011, I went on to gain a MSc in Infection and Immunity from the University of Leicester in 2012.

I obtained my PhD from the University of Glasgow in 2016 where I assessed the impact of dietary fibre and its structure on the production of short chain fatty acids, focusing on propionate. During this time, I used an in vitro batch model of the colon. I continued to use colonic models whilst at the University of Leeds where in addition to batch models I used three stage continuous models to investigated treatment options, and diagnostic methods of healthcare associated infections such as Clostridium difficile and Carbapenemase Producing Enterobacteriacea.

My current research focus on how the structure of different dietary sources affects digestion and fermentation within the gastrointestinal tract in healthy individuals as well as those with gastrointestinal disorders.
