Hall Crannell has been and continues to be a Principal Investigator and Co-Principal Investigator, for a grant from the National Science Foundation. The experimental nuclear physics group consists of three senior investigators, a post doctoral fellow, one to two graduate students and a few undergraduates conducting research on nuclear structure using intermediate and high energy electrons and photons as probes. Major activity at present is concentrated on the use of the tagged photon beam line and the CEBAF Large Acceptance Spectrometer (CLAS) in Hall-B at the Thomas Jefferson National Accelerator Facility in Newport News, VA. This beam line is used to investigate fundamental properties of nuclear matter including studies of the strange quark content of nucleons and nuclei.
The results of this research have been reported in approximately 125 publications as well as in numerous presentations at scientific meetings and seminars at universities and research laboratories.

Hall Crannell was born February 23, 1936, in Berkeley, California. He married Carol Jo Argus June 17, 1961. They have three children: Annalisa, Francesca, and Tasha. Now that the children have left to establish careers of their own, Hall shares his home in Silver Spring, Maryland, with a dog, a variety of turtles, and guests. For recreational activities, Hall enjoys woodworking, opera, and square dancing.
