Research Expertise:
Medical Imaging Physicist: Diagnostic and interventional neurovascular imaging and endovascular devices. We pursue studies in medical physics involving new methods for imaging with x-rays, gamma rays, ultrasound, radioisotopes, and magnetic resonance. As part of the multidisciplanary UB-Toshiba Stroke Research Center, we are investigating new imaging detectors, exposure optimization methods, and means to evaluate and modulate 3D neuro-vascular flow. These imaging methods will be used to aid in the development and application of new therapies our group is developing to replace neurovascular surgical procedures for treatment of pathologies such as aneurysms, stenoses, and malformations. New image-guided, minimally-invasive, catheter-based treatments involve the development of specialized stents, embolic material, filters, and other devices. Additionally, we have quality assurance and radiation safety responsibilities and access to university teaching hospitals which provides a practical training ground for graduate students while they pursue post-graduate research.
