Juliane Weber is a R&D staff member in the Geochemistry and Interfacial Sciences Group at Oak Ridge National Laboratory. Since completing her Ph.D. in geochemistry in 2017 (RWTH Aachen University, Germany), she was a postdoctoral researcher in the Geochemistry and Interfacial Sciences Group at ORNL from 2017-2019, and an associate staff scientist at the Kuiper Materials Imaging and Characterization Facility of the Lunar and Planetary Laboratory at the University of Arizona from 2019-2020. She was an associate R&D staff member from 2020-2024.
Her expertise includes experimental geochemistry including liquid and solid characterization and their application to dynamic mesoscale processes in solutions and at fluid-solid surfaces. Her expertise in characterization methods include neutron/X-ray scattering , atom probe tomography, transmission electron microscopy, Raman spectroscopy and atomic force microscopy. Her research is focused on the influence of microstructure and porosity on reaction kinetics and transport at fluid-solid interfaces, in natural and engineered geomaterials, with the goal of upscaling molecular-scale reaction mechanisms to predict macroscopic transport of contaminants.
Juliane Weber is PI of the DOE BES-MSE funded project "Fundamental mechanisms driving efficiency of CO2 capture using mineral looping" since 2022. Information about the project can be found here: https://www.ornl.gov/project/fundamental-mechanisms-driving-efficiency-co2-capture-using-mineral-looping She is also part of the DOE BES CSBG Core project (led by Andrew G. Stack, ORNL), UNCAGE-ME III EFRC (led by Ryan Lively, Georgia Tech) and a DOE NEUP project (led by Sarah Finkeldei, UC Irvine).
