Keivan Guadalupe-Stassun, Physics

It was at [University of] Wisconsin that my ideas about the importance of combining scholarly practices in research, teaching, and outreach began to crystallize. In addition to carrying out my thesis research, I also became active in math/science education for minorities in the local schools.

Life and Death of Stars


The Life and Death of Stars introduces you to this spectacular story in 24 beautifully illustrated half-hour lectures that lead you through the essential ideas of astrophysics—the science of stars. Your guide is Professor Keivan G. Stassun of Vanderbilt University, an award-winning teacher and noted astrophysicist. Professor Stassun provides lively, eloquent, and authoritative explanations at a level suitable for science novices as well as for those who already know their way around the starry sky.

Keivan Guadalupe-Stassun is a Professor of Physics at Vanderbilt University and an Adjunct Professor of Physics at Fisk University. He is well known for his research on star and planet formation, and leadership of the Fisk-Vanderbilt Masters-to-Ph.D. Bridge Program.

Prof. Guadalupe-Stassun earned his Ph.D. in Astronomy as a National Science Foundation Graduate Research Fellow at the University of Wisconsin–Madison. He was a postdoctoral research fellow with the NASA Hubble Space Telescope Program before joining the faculty at Vanderbilt. His research on the birth of stars, eclipsing binary stars, exoplanetary systems, and the sun has appeared in Nature, has been featured on NPR’s Earth & Sky, and has been published in more than 100 peer-reviewed journal articles. He is a host for Tennessee Explorers, a television show highlighting the work of scientists and engineers to inspire the next generation of scientific explorers, and has served as an expert witness to Congress in its review of approaches for increasing American competitiveness in these fields.

As an MLK Visiting Professor, Prof. Prof. Guadalupe-Stassun was hosted by Professors Ed Berstchinger and Enectali Figueroa-Feliciano in the Department of Physics. During his stay at MIT, he concentrated his efforts on increasing the number of underrepresented minority students in the physics graduate programs. Prof. Guadalupe-Stassun and his MIT colleagues also collaborated on a project to measure trace chemical species in supernova remnants via x-ray and infrared spectroscopy.
