Research Interests

My research interests primarily concern nonperturbative phenomena in quantum field theories, with particular emphasis on the study of hadron formation and confinement in quantum chromodynamics using computer simulations of quarks and gluons. Two past highlights include a first comprehensive determination of the glueball spectrum in pure Yang-Mills and the spectrum of heavy-quark hybrid mesons in the leading Born-Oppenheimer approximation (neglecting light quark loops).  My collaborators and I are currently focussing on ab initio determinations of the excited baryon and meson spectra using lattice QCD Monte Carlo methods.  Our computations are carried out on the NSF XSEDE supercomputers and on machines available through the DOE's INCITE program.
