Biography
Biographical Sketch
Dr. Thomas A. Fleming received his A.B. in Physics from Cornell University in 1982 and his Ph.D. in Astronomy from the University of Arizona in 1988. After spending four years on the science team for the ROSAT X-ray telescope at Max-Planck-Institute for Extraterrestrial Physics in Garching (near Munich), Germany, he returned to the University of Arizona in 1993, where he is now an Astronomer and Senior Lecturer. Dr. Fleming has served on several peer review and users committees for NASA, mostly in the field of X-ray astronomy.
His areas of research include X-ray emission from stars, the nearby stars, very low-mass stars, and white dwarfs. Since 1999, he has been responsible 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.* In 2000, Dr. Fleming received the University of Arizona Provost’s General Education Teaching Award for his innovative techniques in teaching science and astronomy to students not majoring in science.
In 2013, he received an Excellence in Academic Advising award from the University as the Outstanding Faculty Advisor.
Dr. Fleming wrote an extensive 28-chapter set of PowerPoint lecture slides to accompany the textbook, "The Cosmic Perspective," which was published by Addison-Wesley, Inc. He also edited the textbook “Stars,” published by Cognella, Inc., in 2011. In 2005, he appeared in the "Naked Science" TV series episode "The Birth of the Earth" on the National Geographic Channel and in the PBS documentary "Declining by Degrees: Higher Education at Risk."
*Podcasts of the Steward Observatory Public Evening Lecture Series are available on the University of Arizona site on iTunes U starting with the Fall 2009 semester.
