His professional experience included various appointments: junior physicist at the University of Chicago, physicist at Franklin Institute in Philadelphia, instructor at Cornell University, and on to assistant, associate, and professor of Physics at Louisiana State University. He was also a Guggenheim Fellow at the University of Birmingham, England, and visiting professor of physics at the Laboratory of Nuclear Studies at Cornell.

His research interests focused on nuclear photoreactions and photopion production as well as few-hadron problems. Professor Levinger had seven publications, over 100 major journal articles, 36 non-refereed journal publications, and presented 21 talks. He was a fellow of the American Physical Society and a member of Phi Beta Kappa and the Society of the Sigma Xi.
