Profile

Role at ANSTO


Anthony Duff is a structural biologist interested in the structure and function of biological macromolecules. Ultimately, the goal is to understand the mechanism of life at the molecular level. The field of structural biology is inherently an interdisciplinary and collaborative science involving a range of complementary methods.

Prominent examples are X-ray crystallography and nuclear magnetic resonance spectroscopy, which provide precise information on rigid biomolecular structures, and electron microscopy which provides moderate resolution structural information on large assemblies, including membrane structures. To complement these structural techniques, we aim to use small-angle X-ray and neutron scattering to characterise the dynamic structures of biological macromolecular assemblies.
