Background

Benjamin M.W. Tsui, Ph.D., is a Professor in the Johns Hopkins Medicine Division of Medical Imaging Physics within the Department of Radiology and Radiological Science. Dr. Tsui is a researcher who specializes in medical imaging—particularly single-photon computed emission tomography (SPECT), positron emission tomography (PET), and magnetic resonance imaging (MRI).

He also has appointments in the Departments of Electrical and Computer Engineering, Environmental Health Sciences and Biomedical Engineering. He joined the Johns Hopkins faculty in 2002.

His many roles at Johns Hopkins include serving as the Director of the Division of Medical Imaging Physics, as well as on many departmental and School of Medicine committees and boards. He also mentors and advises graduate students.

Dr. Tsui has published approximately 200 scientific articles, contributed nearly 30 chapters to engineering and physics textbooks, and served as an editor and reviewer for many prestigious academic journals.

He has been the principal investigator for scores of externally funded studies, presented some 400 invited lectures and served on numerous federal advisory committees and grant-review groups.
