PhD (University of Queensland)
Summary: Prof McMahon is the Deputy Director of Herston Imaging Research Facility, and Academic Lead Research for the School of Clinical Sciences. She has over 25 years' experience in biomedical imaging and imaging analysis.
Research: Her research interests lie in understanding the neurobiology of language, learning and memory, and the genetic and environmental influences on brain structure and function. When these cognitive systems fail, either due to stroke or a degenerative disease like Parkinson’s, imaging markers of lesion size, position and brain network damage might be able to be used to optimise therapeutic intervention, by providing insights on the best type of therapy. She is also investigating behavioural and neurological markers in children with language development problems, such as autism or specific language impairment. In addition, Prof McMahon collaborates on work looking at musculoskeletal function and MRI markers in whiplash.
Teaching: Prof McMahon contributes to undergraduate lectures in radiation therapy and medical imaging, and has helped develop the online professional development course, MR guided radiation therapy. She has co-developed several hands on practicals at HIRF, for 3rd and 4th year undergraduate courses. She has several higher research degree students.
