Discovered quark jets in e⁺e^- annihilation to hadrons.

Member of Cambridge Electron Accelerator team that measured large cross section for hadron production by e⁺e^- annihilation with large solid angle detector. This cross section was evidence that quark come in three colors.

Member of team that discovered psi (lowest lying charm-anticharm heavy quark resonance in e⁺e^- annihilation cross section) at Stanford Linear Accelerator Center.

Member of SLAC team that discovered second charm-anticharm quark narrow resonance in e⁺e^- annihilation.

As a member of the team that discovered the tau meson, did studies to verify presence of characteristic decay modes of heavy lepton including unpublished study of possible evidence for tau pi + nu(tau) - a characteristic hadronic decay mode of a heavy lepton.

Studies of fragmentation of quarks into hadrons.

Built first stereo jet cell central drift chamber for MarkII SLC.

Evidence for b-flavored baryon production from lambda-lepton correlations in the OPAL experiment at LEP(found by postdoc Xinchou Lou as a member of the Indiana group).

Evidence for strange B meson production from D_s-lepton correlations in OPAL experiment at LEP (found by postdoc Xinchou Lou as a member of the Indiana group).
