QCD is the fundamental theory of quarks and gluons that explains the internal structure and interactions of protons, neutrons and other strongly interacting particles. A full solution of this theory relies upon numerical simulations. I am developing new techniques that have already made such simulations literally thousands of times faster, greatly extending the range of problems that can be studied. I am particularly interested in applications to the physics of hadrons containing heavy quarks. These advances rely upon renormalization techniques, especially effective field theories, that have many other applications in physics. I am pursuing new applications in high-precision atomic physics (QED), heavy-quark physics, nuclear physics, condensed-matter physics, and physics pedagogy.
