magnetic resonance imaging (MRI) • imaging • physics • methods • analysis
My research focuses on the development of advanced methods in magnetic resonance imaging (MRI). MRI is used to image the body, in health or disease, and I aim to make the process faster, more informative, and more accurate. The goal is to develop imaging biomarkers for tissue structure and physiology, so that we can more reliably identify disease with non-invasive MRI. The primary application of my work is in cancer. I am also interested in the integration of physiological MRI approaches, such as perfusion, into cancer treatment planning and assessment. Finally, I have projects in neurological and musculoskeletal imaging, with the same focus on biomarkers.
