I have 25 years of experience and specialize in the field of radiology, neuroradiology, and magnetic resonance imaging, with specific knowledge of magnetic resonance imaging, neuroradiology, magnetic resonance safety and magnetic resonance contrast agents. I have published on such topics as MRI contrast agents, MRI safety issues and MRI physics, and imaging sequence development and design. I have testified on MRI safety, MRI physics and its clinical application, and neuroradiology.
