Donald Geesaman is a Senior Physicist and a former Director of the Physics Division at Argonne National Laboratory. He received his B.S. (1971) from the Colorado School of Mines and M.A. and Ph.D. (1976) from the State University of New York at Stony Brook. After his Ph.D. he joined Argonne National Laboratory and was promoted to Senior Physicist in 1991. He is a fellow of the American Physical Society and the American Association of the Advancement of Science and was elected the Chair of the Division of Nuclear Physics of the APS for 2004-2005. He has served on the Board of the Directors of users groups at M.I.T. Bates, LAMPF, and Jlab, Program Advisory Committees at IUCF, M.I.T. Bates, Jlab, BNL, and GSI, been the chair of the Board of Directors of the Jefferson Lab Users Group and chair of the Jefferson Lab Program Advisory Committee. Dr. Geesaman has also served on the Nuclear Science Advisory Committee and numerous NSAC subcommittees. He was an Associate Editor of Physical Review C and is currently an Editor of Physics Letters B. Dr. Geesaman's recent research focuses on understanding the implications of nucleon substructure in nuclear physics and on understanding the structure of nuclei. This includes measurements of deep inelastic muon scattering at FNAL, measurements of the antiquark distributions of the proton in Drell-Yan experiments at FNAL, tests of color transparency in electroproduction experiments at FNAL, SLAC and Jefferson Lab and several experiments at Jefferson Lab to examine the structure of the proton and its meson fields in the nuclear medium. The nuclear structure work includes electron scattering studies and planning for the advabced Rare Isotope facilities. He is the author of more than 100 scientific publications.
