Experimental elementary particles: charged pion form factor, CP violation in neutral K meson decay, photoproduction and electroproduction of scalar and vector mesons, weak decays of B and D mesons, construction of charged particle detectors, development of software for processing elementary particle physics data, magnetic confinement of neutrons.
I retired in 2010 and am supervising no more Ph.D. theses.
