Naomi works at the Human Nutrition Research Centre and Institute of Cellular Medicine, Newcastle University. She is currently involved in two non-clinical trials on carbohydrates and gut health and using metabolomics to assess dietary intake.

The MAIN study, funded by the Medical Research Council, aims 1) to discover small molecules (metabolites) in urine and blood which reflect habitual consumption of specific foods or food groups important for public health and 2) to validate an efficient population urine sampling procedure suitable for epidemiological studies. This project is a collaboration between Newcastle University, Aberystwyth University and Imperial College London.

She is also part of The DISC study, funded by the Diet and Health Research Industry Club (DRINC) initiative led by the BBSRC, which aims to investigate the impact of non-digestible carbohydrates on biomarkers of gastrointestinal health. This project is a collaboration between Newcastle University and the Institute of Food Research, Norwich.  

Naomi gained her PhD from the School of Biological and Biomedical Sciences, Durham University investigating the role of nuclear lamina proteins in the development and progression of colorectal cancer. As part of her project, she spent time working at Maastricht University, The Netherlands.

Public engagement

Delivered "Discover DNA" workshops at the British Science Festival, 2013 and the Bang Goes the Borders Science Festival, Scotland, 2012 and 2013 to engage all ages in molecular biology.
