Michael Peskin is a professor of theoretical physics at the Stanford Linear Accelerator Center and is currently the head of the SLAC HEP Theory Group. He received his Ph.D. from Cornell University in 1978 and held a Junior Fellowship at Harvard and visiting appointments at CEN Saclay and Cornell before joining SLAC in 1982. His research has dealt with models of new particles and forces that might appear at high energies — supersymmetry, extra space dimensions, string theory, dark matter — and methods for testing these ideas at particle accelerators. He has been involved in scientific publishing issues both informally, as an advisor to the SLAC Library’s information services, and formally, as a member of the board of directors of Annual Reviews, Inc., and of the oversight committee for the journals of the American Physical Society. His essay on the economics of journal publishing can be found at http://www.slac.stanford.edu/~mpeskin/APS-pubs.pdf.
