Dr. Donald Summers，Professor, University of Mississippi, 2002-present.Ph.D., 1984, University of California, Santa Barbara.Memberships American Physical SocietyResearch Interests I am interested in the investigation of the fundamental nature of matter and have collaborated on high energy physics experiments at Fermilab in Illinois and at CERN in Switzerland. At CERN, I worked on the UA1 experiment that discovered the W+, W-, and Z0 intermediate vector bosons. The Nobel Prize was awarded for the discovery of these very heavy particles, which mediate all weak interactions. Work on Mississippi's experiment at Fermilab has involved the application of very high speed data acquisition systems and massively parallel computing systems to studying charm quarks. My experiment, E791, at Fermilab has accumulated the world's largest sample of these heavy quarks. Future interests include analyzing the charm quark as well as investigating broken symmetries in nature through the study of large numbers of beauty quarks at the SLAC b-factory in California.
