Manuel Bautista

Naturalized Venezuelan, Dr. Bautista was actually born in Bogotá, Colombia, on May 20th 1968. BS on the field of Physics from Simón Bolívar University (1990) and in 1997 he obtained his Doctorate on Astronomy from Ohio State University, US. Since then, Dr. Bautista has hold positions as “Faculty Research Associate” at Maryland University and “Senior Research Associate” at Gordon Space Flight Center of NASA. Currently, Dr. Bautista is “Research Associate II” at the Physics Center Department of the Venezuelan Institute of Scientific Investigations (IVIC).
Dr. Bautista has dedicated his effort towards the study of atomic spectrum of astronomic and laboratory plasma. Among his significant achievements stands the work with Dr. Kallman in the development of a computer program and the atomic database XSTAR v.2 for the modeling of photo-ionized plasma spectra which is a tool used by NASA to analyze X-ray spectra from the currently working Chandra and XXM and for the soon-to-be launched Astro-E2 and Constellation-X telescopes.
He was awarded the “Lorenzo Mendoza Fleury” in 2005
