"For the theoretical prediction and experimental demonstration of neoclassical tearing mode stabilization by localized electron cyclotron current drive."


Professor Emeritus James D. Callen received his B.S. (1962) and M.S. (1964) degrees in Nuclear Engineering at Kansas State University. He completed his Ph.D. in Nuclear Engineering (Applied Plasma Physics option) at M.I.T. in 1968. Thereafter he was: a postdoctoral fellow with M.N. Rosenbluth at the Institute for Advanced Study in Princeton (68-69); Asst. Prof. of Aeronautics and Astronautics at M.I.T. (69-72); research staff member, group leader and plasma theory section head in the Fusion Energy Division at ORNL (72-79); Professor of Nuclear Engineering and Physics (79-86), D.W. Kerst Professor of Engineering Physics and Physics (1986-2003) and now Professor Emeritus (03-) at the University of Wisconsin-Madison where he established and led the Center for Plasma Theory and Computation from 1988-2003. He spent year-long research leaves at JET in England (86-87) and Princeton Plasma Physics Laboratory (91-92). His studies and research have been supported by Fulbright, AEC, NSF Graduate and Postdoctoral, and Guggenheim Fellowships. He is a fellow of the American Physical Society (Chair of Division of Plasma Physics in 1986) and the American Nuclear Society. His honors include DoE Distinguished Associate Award, D.W. Kerst Professorship at UW-Madison, Fusion Power Associates Distinguished Career Award, and being elected a member of the National Academy of Engineering (90). He has been involved in many magnetic fusion program and plasma physics activities: early appraisal of tokamak research (DoE WASH-1295, 1974), founder and initial leader (88-91) of U.S. magnetic fusion community Transport Task Force, Chair of FESAC Scientific Issues Subcommittee (95-96), NRC Plasma 2010 Decadal Study Committee Member (05-07) etc. His research interests have focused primarily on theory, modeling and experimental validation of models of collisional effects in low collisionality magnetic fusion plasmas, such as in neutral beam heating, magnetic islandography in tokamaks, neoclassical tearing modes (NTMs), nonideal MHD models, neoclassical toroidal viscosity (NTV), magnetic flutter effects on plasma transport and most recently Coulomb collisional effects on linear Landau damping.
