Jennifer B. Glass is a biogeochemist, geomicrobiologist, astrobiologist, and associate professor of biogeochemistry in the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology in Atlanta, Georgia. Glass received the 2021 Thomas Hilker Award for Excellence in Biogeosciences from the American Geophysical Union.^[1] She was awarded the 2021 Alice C. Evans Award for Advancement of Women from the American Society of Microbiology.^[2]

Glass was born and raised in Olympia, Washington. She earned a B.Sc. of Earth and Space Sciences and Oceanography from University of Washington in Seattle, Washington. She received a Ph.D. in Geological Sciences from Arizona State University under the guidance of Professor Ariel Anbar.^[3] From 2011-2013, she was a NASA Astrobiology Postdoctoral Fellow at California Institute of Technology, in Pasadena, California, in the laboratory of Professor Victoria Orphan.

Glass serves as principal investigator on grants from the NASA Exobiology Program.^[4] She has published research on geochemistry and microbiology in context of the global biogeochemical cycles and astrobiology, including how microbial metal utilization co-evolved with Earth geochemistry and how microbial metabolisms influence greenhouse gas cycles.^[5][6] Her laboratory's current research focuses on microbial interactions with methane clathrate and astrobiology implications.^[7] She has collaborated with Loren Williams on the role of cations including iron as ribozyme cofactors.^[8]
