He has served the American Physical Society in various capacities, including chairing the Topical Group in Plasma Astrophysics (2003-2004). He is the author or coauthor of over three hundred publications in refereed journals, conference proceedings and monographs, in plasma physics, astrophysics, cosmology and applied physics, plus several scores of LLNL programmatic reports. His current research interests include relativistic plasma physics, laser-plasma interactions, high energy density physics, and high-energy astrophysics. He has co-organized a dozen international conferences on astrophysics and cosmology, including the biannual conference on High Energy Density Laboratory Astrophysics (HEDLA), which had its fifth meeting in March 2006 on Rice campus. He was a pioneer of high energy density physics, and contributed to several major reports on HEDP, including the NAS report on High Energy Density Physics chaired by Ron Davidson, and the SAUUL report chaired by Todd Ditmire.
