Strongly coupled field theories are present in almost every field of quantum physics and theoretical predictions are often limited by the non-perturbative nature of these interactions which render the usual perturbative methods invalid. Save for a few special examples, the only way to perform a first-principles calculation of a non-perturbative theory is through computationally demanding lattice methods. My research utilizes lattice field theory in conjunction with effective field theory, limits of large gauge groups, and/or symmetry projections to study strongly coupled behavior in a range of systems including beyond the Standard Model physics (technicolor), hadronic interactions (zero temperature interactions and non-zero temperature/density transitions), and atomic systems (many-body interactions).

At sufficiently high temperatures (~1.5 trillion degrees) nuclear matter undergoes a transition from hadrons (protons, neutrons, and pions) to a deconfined plasma of quarks and gluons. My research focuses on the experimental investigation of this state of matter using the Relativistic Heavy Ion Collider at BNL and the Large Hadron Collider at CERN combined with a theoretical calculation of the properties of the quark gluon plasma using high performance computing available at LLNL, BNL, ANL, and elsewhere. By performing calculations of thermodynamic observables of the quark gluon plasma with validation by experimental data I hope to improve our understanding of the strong interaction at temperatures that existed in the first microsecond after the big bang.

My research is focused on strongly interacting physical theories. In particular, my research has been on Quantum Chromodynamics (QCD) at zero and finite temperature as well as on strongly interacting theories for Large Hadron Collider (LHC) physics and for particle Dark Matter. These studies are challenging and can only be done using Lattice numerical methods on the largest massively parallel supercomputers available. To make this possible I have developed key physics methods as well as have been a core member of the architecture team that built the BlueGene (BG) line of IBM supercomputers and I was the lead hardware designer of the IBM BG/L and BG/P networks. In this decade strong interactions and leading edge supercomputers may indeed unravel some of the known unknowns of QCD and also probe the unknown unknowns of particle physics and dark matter.

Quantum Chromodynamics (QCD) is the fundamental field theory that governs nuclear interactions. However, the interactions between quarks and gluons in the theory are so strong that normal perturbative calculations cannot be performed. My research focuses on using the computational technique of lattice QCD to nonperturbatively calculate physical observables directly from QCD. Lattice QCD involves a combination of HPC resources and GPUs to perform massively parallel calculations on a leadership-class computational scale. I am especially interested in quantities relevant to nuclear physics such as nucleon form factors, parity violating interactions, and scattering parameters, as well as nuclei binding energies.
