Research Statement

I conduct research in high energy theoretical physics. Most of my work involves the solution of the strong interactions of quarks and gluons through numerical simulation on high performance computers. Results of the numerical simulations are compared with results of experiment. They guide our search for new forms of matter, contribute our understanding of the early universe, and may provide clues about still more fundamental physics.
