Number theory is as relevant today as it was two millennia ago, with the advent of high-powered computing and cryptography.
Dr Delbourgo's research interests lie in the area of elliptic curves and modular forms.
His work applies ideas from classical Iwasawa theory and Galois representations, to study the arithmetic behaviour of invariants arising from these objects.
He is also interested in the special values of L-functions, and there is a rich vein of conjectures connecting these L-values with elements in K-groups.
