Areas of Research

Astronomy and Astrophysics

Radioactivity from supernovae and classical novae. Interstellar electron-positron annihilation; X-ray and gamma-ray spectroscopy of radioactivity.

Mark Leising has been on the faculty of the Department of Physics and Astronomy at Clemson since 1991, and served as department Chair from 2011 to 2016 and as Interim Dean of the newly formed College of Science from 2016-2017. He has directed Clemson astronomy labs and the Clemson Planetarium since 1994. He has a B.S. in physics from the University of Notre Dame (1982) and a M.S. and Ph.D. (1987) in space physics and astronomy from Rice University.

Prior to joining the Clemson faculty he was an astrophysicist for the U.S. Naval Research Laboratory (1988-91) and a research associate for the National Research Council/Naval Research Lab (1986-88). While at Clemson, he has taken leave to work at other institutions including the Max Planck Institut fur Extraterrestrische Physik in Germany as a Humboldt fellow and the Observatoire du Midi- Pyrenees /CESR in Toulouse, France.

Among research highlights, he and collaborators made the first detections of radioactive debris in a supernova explosion, produced the first map of electron-positron annihilation from the Milky Way, and he predicted the detectability of supernova radioactivity in X-rays, which has since been realized. He has directed the disertations of eight Ph.D. graduates and numerous M.S. and B.S. students.
