About Daniel

Daniel grew up in Tasmania, and then moved to England to do his PhD.

He subsequently undertook postdocs in Paris and Strasbourg, before obtaining a permanent position at the University of Nottingham.

Daniel later moved to Melbourne for a four year period, and started at the University of Waikato in 2012.

Research Interests

Number theory is as relevant today as it was two millennia ago, with the advent of high-powered computing and cryptography.

Daniel'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.

Research Supervised

PhD students: Hamish Gilmore (Waikato), Chao Qin (Waikato); Lloyd Peters (Monash); David Sim (Nottingham, 2nd Supervisor); Thomas Ward (Nottingham); Paul Smith (Nottingham)
