Dr Halperin received the B.S degree in physics with highest distinction from Purdue University, the M.A. degree in physics from the University of California, Berkeley, and the M.D. degree from Louisiana State University, New Orleans, Louisiana. He is a member of Phi Beta Kappa, an Established Investigator and Fellow of the American Heart Association, and a McClure Fellow of the Johns Hopkins University Applied Physics laboratory.

Dr. Halperin is currently a Professor of Medicine, Radiology and Biomedical Engineering at the Johns Hopkins Medical Institutions. He is the co-Director of the Cardiovascular Imaging Center of Excellence. He serves on the editorial board of the journal Resuscitation, and is a past chair of the national American Heart Association Advanced Cardiovascular Life Support Subcommitte and a past member of the Emergency Cardiac Care Committee. Ten of his students have received young investigator awards from the American Heart Association and Heart Rhythm Society, and he has ongoing support from the National Institutes of Heath for his research programs. He has over 120 peer-reviewed publications and over 20 patents issued.
