Goldschmidt 2024
Join Pacific Northwest National Laboratory (PNNL) at the 2024 Goldschmidt International Conference on Geochemistry
Chicago, Illinois and Hybrid
Organized by the Geochemical Society and the European Association of Geochemistry, Goldschmidt is a prominent, annually occurring, international conference on geochemistry and related subjects. The conference features a mix of hybrid and in-person workshops, lectures, poster presentations, and social mixers for attendees.
PNNL geochemists will be attending the conference to deliver new ideas and discuss current issues and associated topics within the field.
Meet Our Featured Presenters
Kevin Rosso
Dr. Rosso is a Laboratory Fellow and leads the Department of Energy Basic Energy Sciences-sponsored Geosciences program at PNNL. He'll be giving a keynote talk in the session “Novel, Computational, Data-Driven and Multi-Scale Approaches for Advancing Geochemistry” overviewing recent research on fundamental computational molecular simulation of structure and reactivity at iron oxide / water interfaces.
Ben Legg
Dr. Legg is a chemist in the Geochemistry group of the Physical Sciences Division at PNNL. Dr. Legg will be delivering a presentation on “Electrostatic forces drive the formation of nanostructured hydroxide films on mica” in a technical session on “Geochemical and Environmental Aspects of Surfaces: Processes and Modeling.”
Jackie Hager
Jackie Hager is an Earth scientist who is primarily focused on two topics: groundwater remediation—specifically on testing ion exchange resins for pump-and-treat applications—and glass corrosion in the environment, specializing in evaluating biocorrosion of glasses by soil and subsurface microbes. She will be presenting on the “Role of Microbes in Glass Dissolution with Implications for Radioactive Waste Disposal.”
Sarah Saslow
Dr. Saslow is a chemist whose research has focused primarily on the immobilization of radionuclides and co-mingled contaminants that persist in nuclear waste streams or that require remediation from the Hanford subsurface. Along with completing a talk on “Strategies of Nuclear Waste and Infrastructure Management towards Decarbonization Efforts in the Energy Sector,” she will also be presenting a poster.
Guohui Wang
Dr. Wang is an Earth scientist whose work has focused primarily on waste stream radionuclide treatment by waste forms and iron spinel, subsurface transport and in situ contaminants remediation technology, and gas-phase transport in porous media, as well as impacts of CO2 sequestration on groundwater quality. He will be giving a talk titled, “Technetium Removal from Aqueous Waste Streams by Ferrous Iron Minerals and Subsequent Stability in Grout Waste Forms.”
Benjamin Parruzot
Dr. Parruzot is a materials scientist whose work focuses primarily on the study of the long-term alteration of low-activity as well as high-level nuclear waste glasses. He will be presenting on “Multiphase Waste Form Performance Evaluation: Laboratory Testing Techniques for a Wide Range of Materials.”
Nick Ward
Dr. Ward is an Earth scientist and team leader of the Environmental Biogeochemistry team in the Coastal Sciences Division. His work primarily focuses on carbon as a currency that gets exchanged across this continuum and seeks to understand how water flow, plants’ productivity, and cycling of nutrients and redox-sensitive species collectively mediate these carbon exchanges. He will be giving a talk titled “Novel Environmental Conditions Stimulate Organic Carbon Reactivity Along the Terrestrial-Aquatic Continuum.”
Jianqiu Zheng
Dr. Zheng is an Earth scientist who is particularly interested in integrating multi-omic data into reaction-based biogeochemical models to build mechanistic linkage between microbial metabolism and ecosystem dynamics. She will be presenting, “Observing and Modeling Biogeochemistry in Rapidly Changing Terrestrial and Aquatic Ecosystems.”
