Galaxy Evolution Explorer Media Telecon: Aug. 15, 2007, 1 p.m. EST (10 a.m. PST)
Christopher Martin, the principal investigator for the Galaxy Evolution Explorer, is a professor of physics at the California Institute of Technology in Pasadena. His interests include research in galaxy evolution, interstellar and intergalactic medium, the end-states of stellar evolution and novel ultraviolet and optical instrumentation. Martin has a long history of using ultraviolet experiments to study galaxy evolution and the interstellar medium. His work includes several sounding rocket and space shuttle experiments, and he is leading the Faint Intergalactic Redshifted Emission Balloon, an experiment using a balloon-borne ultraviolet telescope. He is also working on an optical instrument that will detect and map the intergalactic medium. The instrument is on the Hale telescope at Palomar Observatory near San Diego. Martin obtained his bachelor's degree from Oberlin College, Ohio, in 1978 and his doctorate from the University of California, Berkeley, in 1986. Prior to joining the Caltech faculty, he was a faculty member in the physics department at Columbia University, New York, N. Y.

Michael Shara is the curator in the department of astrophysics at the American Museum of Natural History and an adjunct professor of astronomy at Columbia University, both located in New York City. Prior to joining the museum, he spent 17 years with the Space Telescope Science Institute in Baltimore, Md., where he was responsible for the peer review and proposal selection committees for the Hubble Space Telescope. He also served as the project scientist for the Guide Star Catalog and Digitized Sky Surveys, which supported Hubble operations. Shara received his doctorate from Tel-Aviv University in Israel, and he holds a master's degree and bachelor's in physics from the University of Toronto, Ontario, Canada. Shara's research interests include the structure and evolution of novae and supernovae; collisions between stars and the remnants of those collisions; and the populations of luminous and erupting stars inhabiting star clusters and galaxies. He is editor of the book "Stellar Collisions, Mergers and their Consequences." + Full resolution (6Mb)
Mark Seibert is a postdoctoral research associate at the Observatories of the Carnegie Institution of Washington in Pasadena, Calif. His research interests focus on extra-galactic star formation and galaxy evolution. He has particular interest in developing techniques to understand and correct the effects of dust attenuation on ultraviolet and optical tracers of star formation. He is applying these methods to normal, starburst, interacting and high redshift galaxies. These extra-galactic studies have also led to his research on the ultraviolet properties of hot sub-dwarf stars, cataclysmic variable stars and evolved stellar populations. Seibert obtained his doctorate in astrophysics from Johns Hopkins University, Baltimore, Md., in 2003. He was a postdoctoral scholar at the California Institute of Technology in Pasadena for three years and joined the Carnegie Institution of Washington, also in Pasadena, in 2006.
