MAJOR RESEARCH AREAS

Imaging of Acute Ischemic Stroke: Stroke is a leading cause of death and disability worldwide. We investigate novel diagnostic paradigms including risk-stratification tools, specialized CT/MRI protocols, imaging workflows, and novel imaging modalities to improve the detection of ischemic stroke.

Diagnostic Testing Utilization and Cost: Diagnostic test utilization is a major contributor to healthcare costs. We investigate strategies to maximize the value of advanced imaging, in particular for emergency, traumatic, and neurologic conditions. Optimizing patient selection for imaging can improve both outcomes and costs.

Improving Diagnostic Accuracy in Radiology: Minimizing diagnostic error — detection error within radiology specifically — is among the most powerful ways to ensure quality care and patient safety. We develop practical strategies, educational materials, and clinical decision support tools to improve diagnostic accuracy in radiology.

Workflow Efficiency: Results of radiological examinations are often the rate-limiting step in patient triage, management, and disposition. Interpretive efficiency is a major determinant of radiologist wellbeing and professional satisfaction. We develop practical tools to optimize radiologic workflow efficiency.
