Jean M. Quashnock is a researcher in the Sloan Digital Sky Survey (SDSS), also known as the Map of the Universe Project, an effort to catalog and map 100 million galaxies. His research interests include cosmology, large-scale structure in the universe, high-energy astrophysics and gamma-ray bursts, and absorption-line systems in quasar spectra. His work has been published in more than 60 scientific publications.

Professor Quashnock is an active member of the American Astronomical Society, the American Physical Society, the American Association of Physics Teachers, and Sigma Xi. He serves as an associate at the University of Chicago, where he previously was a lecturer and a research scientist, and collaborates with researchers there, in the Department of Astronomy & Astrophysics, and at Fermilab. He also has lectured in the Medical Physics Department of the College of Health Professions, Rosalind Franklin University.

Professor Quashnock earned his B.Sc. in physics from McGill University, and Ph.D. from Princeton University in 1990. He studied the dynamics of topological defects and the effects of phase transitions in the early universe (The First Three Microseconds: Cosmic Strings, Axions, and Magnetic Fields). He has a particular interest in acoustics and the physics of music. He sings tenor in various choirs in Wisconsin. After doing postdoctoral work at the University of Chicago, he joined the Carthage faculty in 1999.

What students say

“I find Professor Jean Quashnock’s excitement for physics infectious, and he’s an excellent teacher. He knows just the right pace at which to teach, giving you enough time to understand the material, but also making sure it’s not too easy.” — KelliAnn Anderson, ’14
