Steve Sharpe joined the particle theory group in the Physics Department at the University of Washington in 1988. Current research interests include lattice gauge theory, and in particular the calculation of weak matrix elements, and hadron spectroscopy. Current graduate student is Andrew Lytle. Previous graduate students are Keith Clay (joint with Steve Ellis, presently on faculty at Green River Community College), Yan Zhang (was postdoc at Beijing U., present whereabouts unknown), Noam Shoresh (joint with David B. Kaplan, postdoc at Boston U, now postdoc at Harvard center for genomics research),. Ruth Van de Water (presently postdoc at Fermilab) and Jackson Wu (presently postdoc at Triumf, Vancouver).

Publications
I organized a summer school at the INT in 2007 on ``Lattice QCD and its applications''.

Most lectures are posted on the INT web site, but here is a backup.
Student talks and Student posters.

USQCD collaboration, which has obtained support from DOE for computational resources and support.
I am a co-PI on a SciDAC2 (Scientific Discovery through Advanced computing---round 2) proposal aimed at creating a national infrastructure for lattice gauge computing.
I am calculating the kaon B-parameter and other matrix elements using improved staggered fermions, using USQCD resources. The project web page is here .
Lecture notes, unpublished contributions to recent meetings, and upcoming meetings:

Lattice QCD: Present and Future, Orsay, France, April 14-16, 2004.
- Talk on the computational requirements for future calculations of weak matrix elements.
ILFT Workshop on Perspectives in Lattice QCD, Nara, Japan, Oct 31-Nov 11, 2005.
- Lectures on "Applications of chiral perturbation theory to lattice QCD" (published by World Scientific).
"Subatomic physics and lattice calculations", GDR meeting, CNRS, Marseille, June 25-27, 2008.
- Updated lectures on "Applications of chiral perturbation theory to lattice QCD" . These lectures describe the use of effective field theories to extrapolate results from the parameter region where numerical simulations of lattice QCD are possible to the physical parameters (physical quark masses, infinite volume, vanishing lattice spacing, etc.). After a brief introduction and overview, I discuss three topics:
  - (1) Chiral perturbation theory in the continuum, and lessons for lattice calculations;
  - (2) The inclusion of discretization effects into chiral perturbation theory, focusing on the application to Wilson and twisted-mass lattice fermions;
  - (3) Extending chiral perturbation theory to describe partially quenched QCD, and (this is new) a discussion of the relationship of the possible ambiguity in the definition of $m_u=0$ and the existence of continuum PQ theories.

Plenary talk at Lattice 2006, Tucson, Arizona, July 23-28, 2006
- Rooted staggered fermions: good, bad or ugly? (discussing validity of rooting trick used when simulating with staggered fermions).
