After making heathier crisps and lecturing in Chile, and working for the UN, Jerusa Brignardello is now looking for fingerprints of different diets in human waste. 

At this Day in the life talk Jerusa will take your questions on dietary science and nutrition, and how to address public health challenges through what we eat. Join her to explore a career that started out in her Chilean homeland, saw her work for the Nobel prize-winning UN World Food programme, and now sees her carrying out a PhD in metabolics at Imperial. 

During this talk Jerusa will discuss how the potential in microbiome science for smart, personalised nutrition must be balanced with tackling the immediate real-world challenges around malnutrition through more traditional food interventions and public health policy.
