Biography
2010-2015: Postdoctoral researcher at King’s College London on a BBSRC DRINC grant investigating the effects of plant cell walls on the bioaccessibility of starch and lipid from plant foods using a mixture of in vitro, in vivo and in silico methods. For the last two years I was a teaching fellow in the Nutrition and Dietetics department with responsibility for the 1st year nutrition students. 2008-2009: Research assistant at the Institute of Food Research, Norwich in the Metabolomics group. Analysis of small molecule metabolites from botanical and microbial samples by NMR and MS, in particular the metabolic differences between Salmonella bacteria in liquid culture and within a gel. 2004-2008: PhD student
Research Interest
The behaviour of cell walls during digestion is affected by the type and order of food processing methods used, as well as the composition and structure of the walls. Chewing then produces ruptured or intact cells, where the nutrients are completely accessible to digestive enzymes or naturally encapsulated, respectively. This can result in huge differences in the bioavailability of nutrients. My research focuses on determining how cell wall composition may be used to predict the cell wall behaviour after food processing and chewing to better understand nutrient availability in the diet.
