Marie Sklodowska Curie Individual Fellowships aim to support the mobility of researchers between different institutions in Europe, such that they can learn new techniques and develop skills to stimulate their research. In Dr Dimeloe’s case, she is returning to the UK after spending four years as a post-doctoral research fellow in Basel, Switzerland. There, she learnt how to measure the dynamic changes in metabolism that occur in immune cells during an immune response, to define the molecular pathways involved and, importantly, how these changes underpin the role of immune cells in clearing infections and cancers.
