Research Interests

My research work has focused primarily on developing new techniques and technologies for high-field magnetic resonance imaging (MRI), and, more recently, on developing new methods for early diagnosis of cartilage degeneration in the hip joint. I am an expert in parallel MRI techniques, which employs many-element arrays of RF detectors to accelerate MR image acquisition and multiple radiofrequency (RF) transmit coils both to accelerate MR signal excitation and to compensate for signal inhomogeneities at high field MRI. I have developed the dyadic Green's function (DGF) methodology for fast electrodynamic simulation of RF coil performance, I have introduced the concept of ultimate intrinsic specific absorption rate (SAR), the theoretical smallest radiofrequency (RF) power deposition for a given magnetic resonance (MR) excitation, and I have shown for the first time ideal current patterns corresponding to optimal performance, which can be used as a guide for optimizing the design of many-element RF coil arrays. I have also developed a method to assess the quality of receive coils against ultimate intrinsic signal-to-noise ratio (SNR), the theoretical largest SNR for a given imaging task. Since 2010, my work has expanded into a highly translational research area, which is the application of MR-based biochemical imaging techniques for the evaluation of the hip joint in patients with femoroacetabular impingement (FAI), a medical condition for which early detection can help delaying or preventing the onset of osteoarthritis. In the future I plan to combine my two main research interests and develop innovative RF coils to improve the diagnostic power of high-field MRI in musculoskeletal applications.
