My current work is focused on two research areas:
1. Understanding the role of epigenetic mechanisms in the so-called “nutritional programming” of adult diseases, a phenomenon by which suboptimal diet during critical periods of development is associated with risk of metabolic diseases such as type 2 diabetes and obesity in later life. I’m particularly interested in uncovering the role of altered promoter-enhancer interactions in this phenomenon.
2. I’m also studying the molecular mechanisms by which the imprinted insulin-like growth factor 2 (Igf2) gene regulates the normal development of pancreas and placental vasculature during late gestation. For this purpose I’m using novel in vivo conditional deletions in the mouse combined with in vitro assays.
I’m a member of Miguel Constancia’s group and I’m currently funded by the MRC-MDU.
