Researcher, Griffith Institute for Drug Discovery, Griffith University

Originally from Northern Ireland, Dr Róisín McMahon is a research scientist at the Griffith Institute for Drug Discovery at Griffith University, Australia.

Dr McMahon read Natural Sciences at the University of Cambridge before undertaking postgraduate training at the University of Oxford in protein crystallography. She received a DPhil in 2010 for structural investigation of how immune proteins malfunction in autoimmune diseases such as multiple sclerosis.

Her research interests are in structural biology, particularly protein crystallography as applied to the discovery of new antimicrobial drugs. Resistance to antibiotics is one of the great public health crises of the modern era. As resistance rates grow we face a possible future where antibiotics are no longer effective and common infections once again kill. Dr McMahon’s interests are in the identification of new antimicrobial targets and the development of new antimicrobial drugs using rational structure based drug discovery approaches.
