Grace Barker is a third year PhD student in the Department of Metabolism, Digestion and Reproduction at Imperial College London.
She studies the metabolic interactions between an individual’s body and the gut microbiome, the microbial life that lives in our body. She uses nuclear magnetic resonance (NMR) and mass spectrometry (MS) to understand how diets, specifically supplemented fibre influence the development of colorectal cancer (CRC).
Collaborations connect Grace’s work to communities around the world, including a project working with a community in Alaska that show a higher risk to CRC due to a high consumption of meat and low levels of fibre in their diet. Supplementing their diet with fibre should help guide Grace and her collaborators to better understand the overall effects of fibre supplementation on lowering CRC risk.
We also discuss Grace’s life as a PhD student, some of her hobbies and what she thinks makes her a scientist.

As with Isabelle, I also thanked Grace with cake. If you’d like to be interviewed as part of our series of The Voices Behind Science, please email firstname.lastname@example.org
We promise to have a lockdown friendly thank you that’s just as good as cake!
