Project Geochemist, Ph.D.
Dr. Jansen received her Ph.D. in Geochemistry from the University of Colorado at Boulder. During her studies, she investigated iron oxidation reactions in ultramafic rocks that generate hydrogen and highly alkaline fluids in the Sultanate of Oman. She gained a deep knowledge of iron metal cycling in subsurface fluids and learned a variety of analytical and spectroscopic techniques to characterize geochemistry and mineralogy.
Dr. Jansen’s postdoctoral studies investigated the beneficial reuse of oil and gas waste for agricultural irrigation. She conducted greenhouse studies to determine the effects of produced water irrigation on plant immune response, soil health, and soil microbial community composition.
Dr. Jansen has a broad scientific background with a focus on geochemistry. She received her Bachelor’s degree in Environmental Geosciences from the University of Notre Dame. In her undergraduate work, she investigated the adsorption of mercury and arsenic to microbial cells as a potential remediation strategy. She also synthesized and analyzed minerals incorporating neptunium and uranium into their crystal structures to characterize nuclear waste crystallization.
