Biography
Professor Katie McMahon is a highly esteemed academic, currently holding the positions of Deputy Director of the Herston Imaging Research Facility and Academic Lead for Research at the School of Clinical Sciences, Queensland University of Technology (QUT). With an illustrious career spanning over 27 years in biomedical imaging and analysis, she is a leading authority in her field.Prof. McMahon's groundbreaking research delves into the intricate neurobiology of language, learning, and memory, exploring the profound genetic and environmental influences on brain structure and function. Her pioneering work is pivotal in unraveling the complexities of cognitive system failures associated with conditions such as stroke, epilepsy, and brain tumors. Additionally, she investigates critical behavioral and neurological markers in children with language development challenges, including autism and specific language impairments. Her collaborative efforts extend to examining musculoskeletal function and identifying MRI markers in whiplash injuries.
Beyond her research, Prof. McMahon is a dedicated educator, contributing significantly to undergraduate courses in radiation therapy and medical imaging. She has also developed innovative online professional development courses in MR-guided radiation therapy. Her commitment to nurturing the next generation of scientists is evident through her mentorship of numerous higher research degree students.
For those interested in exploring collaborative projects or seeking her expertise, Prof. McMahon welcomes inquiries and discussions.
