Research efforts center around the quark model as it pertains to low energy strong, electromagnetic, and weak interactions: (1) nonperturbative QCD, (2) perturbative QCD, (3) scalar mesons, (4) quark wave functions, (5) particle mixing, and (6) weak quark decays. Also, nonperturbative properties of classical and quantum field theories are under study. Research is briefly described. (WHK)
