Jeremy Richardson L. Jeremy Richardson
NASA Postdoctoral Fellow
NASA's Goddard Space Flight Center, Greenbelt, Md.

Dr. Jeremy Richardson completed his tenure as a NASA postdoctoral fellow at NASA's Goddard Space Flight Center, Greenbelt, Maryland, on February 2, 2007. He was recently appointed as the first John Bahcall Public Policy Fellow at the American Astronomical Society. Richardson's research focuses on the characterization of extrasolar planets using spectroscopy and photometry. His doctoral dissertation work was among the first attempts to detect the signatures of transiting extrasolar planets by monitoring the time when the planet disappears behind the star during secondary eclipse. In 2005, Richardson was a member of one of the first teams to use this technique to detect light from an extrasolar planet. He received his doctorate in physics from the University of Colorado, Boulder, in 2003, and his bachelor's degree in physics from West Virginia University, Morgantown, West Virginia, in 1997.

Carl GrillmairCarl Grillmair
Research astronomer
NASA's Spitzer Science Center at the California Institute of Technology, Pasadena, Calif.

Dr. Carl Grillmair is an associate research scientist at the Spitzer Science Center of the California Institute of Technology, Pasadena, Calif. His research has focused on extrasolar planets, star clusters, dark matter and galaxies. Among other things, he is known for his recent discovery of several enormous stellar streams orbiting the Milky Way. Grillmair received his undergraduate degree in astrophysics from the University of Calgary, Alberta, Canada, in 1983, and his doctorate in 1992 from the Australian National University, Canberra, Australia.

Mark SwainMark Swain
Research scientist
NASA's Jet Propulsion Laboratory, Pasadena, Calif.

Dr. Mark R. Swain is a deputy director of the Center for Exoplanet Science at NASA's Jet Propulsion Laboratory, Pasadena, California. He is the principal investigator of a project to develop high dynamic range spectroscopy techniques for characterizing exoplanets. His work includes observations with NASA's Spitzer Space Telescope, Hubble Space Telescope, the NASA Infrared Telescope Facility, and the European Southern Observatory Very Large Telescope. Swain received his Ph.D. in physics and astronomy from the University of Rochester, New York, in 1996. After his post-doctorate work at Cornell University, Ithaca, New York, he joined JPL in 1998. As a member of NASA's Keck Interferometer project, he worked on the development of the differential phase observing technique for exoplanets, instrument integration and testing, and led the first observations of an extragalactic source with an infrared interferometer. Swain is currently a senior member of the technical staff at JPL and has held visiting appointments at the Max-Planck Institute for Astronomy and the Laboratory of Astrophysics at the Observatory of Grenoble.

Alan BossAlan Boss
Staff research astronomer
Carnegie Institution of Washington

Dr. Alan Boss is a research staff member at the Carnegie Institution's Department of Terrestrial Magnetism in Washington, D.C. Boss earned his doctorate in physics from the University of California, Santa Barbara, in 1979, spent two years as a postdoctoral fellow at NASA's Ames Research Center, Moffett Field, Calif., and joined the Carnegie staff in 1981. Boss's theoretical research focuses on the formation of stars and planetary systems, and he has been helping NASA plan its search for extrasolar planets. Boss is a member of the American Academy of Arts and Sciences, and is a fellow of the American Association for the Advancement of Science, the Meteoritical Society and the American Geophysical Union. He is the chair of the International Astronomical Union's working group on extrasolar planets and is charged with maintaining its official list of planets. His popular book about the search for planets outside the solar system, "Looking for Earths: The Race to Find New Solar Systems," was published in 1998.
