Róisín McMahon is a postdoctoral researcher working at the Institute for Molecular Bioscience at the University of Queensland. Her research interests are in the application of structural biology, particularly macromolecular crystallography for protein structure-function investigations. Studying proteins at a molecular level, particularly those involved in human disease and bacterial pathogenesis, can help unpick how they function in health and disease, and provides a vital platform for new the development of new therapies. She read Natural Sciences at Cambridge, and holds a DPhil from the University of Oxford. She has a webpage and tweets @roisinmcmahon
