Dr. Fleming's areas of research include X-ray emission from stars, the nearby stars, very low-mass stars, and white dwarfs. Since 1999, he has been resposible for public outreach and coordination of the astronomy general education program at Steward Observatory. In particular, he serves as organizer and host of the Steward Observatory Public Evening Lecture Series, the observatory's major vehicle for disseminating information on astronomy and space science to the general public since 1922.

Fulvio Melia is Professor of Physics and Astronomy at the University of Arizona, and is a member of the Theoretical Astrophysics Program. He is also the Series Editor for Theoretical Astrophysics with theUniversity of Chicago Press. His overall research theme is the study of the physics of matter and radiation in the extreme conditions encountered near compact astrophysical objects, such as neutron stars and black holes. The main areas of current interest include the particle acceleration and radiative emission in Active Galactic Nuclei, the Galactic center, especially with regard to the massive black hole candidate Sgr A*, electron-positron plasmas near the event horizon of Cygnus X-1-like objects, and accreting neutron stars and white dwarfs in binary stellar systems. presented November 5, 2012.
