Holly Jayne Stein is an American geologist who is a senior research scientist and a professor at Colorado State University. She established the AIRIE (Applied Isotope Research for Industry and the Environment) Program and has led the center since 1995. Her research focuses on the development of the rhenium-osmium (Re-Os) geochronometers.[1] In 2015, she was elected Geochemistry Fellow of the European Association of Geochemistry.[2]
Stein attended Western Illinois University and completed her bachelor’s degree there. She received her master’s and doctorate degrees from the University of North Carolina at Chapel Hill.[3]
Stein joined the Department of Geosciences at Colorado State University (CSU) as a senior research scientist in March 1998. She is a professor at CSU and Center for Earth Evolution and Dynamics at the University of Oslo, Norway.
Stein established AIRIE Program in 1995, which is located in CSU. She has been leading the team as a director to date. AIRIE develops Re-Os geochronology and applies the dating techniques to explore various fields ranging from mass extinction to energy resources. The team investigates metallogenesis on ore and petroleum deposits to understand their relationships to geologic processes. AIRIE is also known for its technology of dating molybdenite.
In 2004, Stein developed innovative pyrite Re-Os geochronology and contributed to revealing the presence of a significant amount of atmospheric oxygen in 2.32 billion years ago. Her geochronological analysis provided a better understanding of diverse sedimentary and paleoclimatology mechanisms.
