He has served as Associate Editor & Reviewer for a number of professional journals including "Medical Physics" & is a former member of the ACR Mammography Interpretive Skills Assessment Committee. He is a fellow of the AAPM and of the SPIE and has received the Lifetime Service Award from the ABR.

Dr. Bednarek is a research faculty member of the Canon Stroke and Vascular Research Center & former Clinical Medical Physicist at the Erie County Medical Center. He has taught medical imaging physics & radiation safety for over 40 years to radiology residents, graduate students, medical students, and hospital staff. He has been engaged in research in region-of-interest imaging including development & evaluation of limited-field-of-view, high resolution real-time imaging detectors with specific application to neuroimaging. Recent work has focused on methods for determination of patient and staff radiation dose and development of a real-time dose-tracking system for interventional fluoroscopic procedures. He is a founder and current director of the UB Museum of Radiology and Medical Physics.
