Dr. Richard was Dr. Siewerdsen’s first PhD student in Medical Biophysics at the University of Toronto. Sam’s research involved the first development of cascaded systems analysis and task-based detectability index for dual-energy imaging. His work guided the development of new dual-energy radiography systems for early-stage lung cancer detection. Sam continued in a postodoctoral fellowship and as Assistant Professor at Duke University, where he extended task-based analysis to computed tomography in collaboration with Dr. Ehsan Samei. He is now a Project Leader at the Carestream Health Research & Innovation Labs, where he oversees all pre-clinical evaluations of new medical imaging products and manages collaborations with clinical sites.
