I have 25 years of experience, and specialize in the field of diagnostic radiology with specific knowledge in the areas of trauma, chest, and body imaging as well as positron emission tomography (PET) imaging, computed tomography (CT) , picture archival and communications system (PACS) and voice recognition systems. I have published on such topics as CT Imaging in the Emergency Room, soft tissue calcification and cervical spine injury. I have testified on traumatic injuries. I have had many years of experience in both the academic and private practice spheres, including working in the nighthawk radiology program established at the University of Pennsylvania.
