Early life and education edit
Stein studied cellular and developmental biology at the University of Colorado Boulder. She moved to Oregon State University for her doctoral research, where she studied the physiology of ammonia oxidising bacteria.[1] Stein was a postdoctoral scholar at the Jet Propulsion Laboratory, where she built a mobile field lab to study biogenic gas fluxes in situ. The laboratory could concentrate gases that evolved from a microbial surface, measure the physiochemical changes that take place during a diurnal cycle and characterise a large variety of gases simultaneously.[2]
Research and career edit
Stein joined the faculty at the University of California, Riverside in 2001, where she investigated the role of soils and microorganisms in the flux of carbon-based gases and other greenhouse gases in and out of soils.[3][4] She performed a whole genome analysis of ammonia oxidising bacterium.[5] She moved to the University of Alberta in 2008, where she was made Professor in 2016.
Her research considers nitrogen, methane oxidation and carbon fixation in bacteria.[6] She has proposed that gene editing could be an effective strategy to combat climate change.[7] The Haber-Bosch process, the main industrial procedure ammonia production, has dramatically impacted the Nitrogen cycle.[8][9] This has resulted in excess greenhouse gasses and over production of nitrate, which results in the eutrophication of ground water.[8] In an effort to slow the runaway nitrogen cycle, Stein has proposed to replace chemical fertilisers with nitrification inhibitors.[8] Specifically, she looks to commercialise biological nitrification inhibitors.[8]
In 2019 she was one of 11,000 scientists who signed a letter declaring a climate emergency.[7] Stein was awarded the 2022 Killam Award for Excellence in Mentoring.[10]
