The Manufacturing Energy Efficiency Research & Analysis (MEERA) Group at ORNL is seeking a Postdoctoral Research Associate to engage in research and technical support for industrial decarbonization workforce development. The ideal candidate should have a strong background in mechanical engineering, industrial energy systems, renewable energy, decarbonization, or other related fields. They should also possess experience in industrial workforce development and technical training.

The Environmental Sciences Division (ESD), http://www.esd.ornl.gov at Oak Ridge National Laboratory (ORNL), http://www.ornl.gov seeks a highly motivated and creative individual skilled in biogeochemistry or stream ecology to work on a project investigating the effects of coupled geochemical, microbiological, and hydrological processes on mercury (Hg) transformations leading to the formation and destruction of methyl mercury in sediment-surface water systems.  Current research at ORNL in this area spans from the molecular to the field scales although for this position work will be conducted at the laboratory microcosm to field scales.  The integration of field, laboratory, and simulation research will be used to inform decisions related to environmental remediation and long-term stewardship of terrestrial and aquatic systems. 

We are seeking a Postdoctoral Research Associate who will support the Geochemistry and Interfacial Sciences Group, Chemical Transformation Section in the Chemical Sciences Division (CSD), Physical Sciences Directorate (PSD) at Oak Ridge National Laboratory (ORNL). The postdoctoral researcher will focus on combined carbon capture and conversion in ionic liquids and aqueous electrolytes. 

This position is funded by an Energy Research Frontier Center (EFRC) – the Center for Understanding and controlling Accelerated and Gradual Evolution of Materials for Energy (UNCAGE-ME III). The goal of this research project is to gain a fundamental understanding of how degradation of catalysts during combined capture and conversion of carbon dioxide using ionic liquids and aqueous electrolytes.

Specifically, how the structure of the electrocatalysts and the surface chemistry of CO2 reduction evolves as a function of the nature and concentration of the contaminants in both aqueous electrolytes and ionic liquids; and capture and conversion can be combined in ionic liquids. Approaches include both experimental and computational studies of kinetics and reactivity, spectroscopic identification of surface reactants and mechanisms under in situ and operando conditions.

Under general supervision, the Postdoctoral Research Associate will conduct research in synthesizing Cu-based electrocatalysts, measuring electrochemistry of CO2 reduction, and conducting in situ measurements (atomic force microscopy) for mechanistic understanding of degradation. The postdoc will work in close collaboration with the EFRC team members at ORNL and other EFRC PIs, and have opportunities to visit members of other EFRC institutions including Lehigh University, Georgia Tech and University of Michigan.  This research program will take advantage of resources at ORNL including the Spallation Neutron Source (SNS) and the Center for Nanophase Materials Sciences (CNMS). The environment at ORNL is highly collaborative and crosscutting research exists between the CSD and other Divisions at ORNL.

This involves the development of experimental plans to examine material properties such as thermal diffusivity, thermal conductivity, and thermal expansion – material properties critical to understanding target behavior during irradiation in the High Flux Isotope Reactor (HFIR). This could also involve development, validation, and deployment of new physical and analytical testing methods towards improving our understanding of unique target materials. You will be working with scientists, engineers, technicians, and safety and quality assurance staff to support material testing and fabrication efforts that advance HFIR isotope production targets. We are seeking a person who can be a team player with excellent attention to detail, critical thinking ability, and strong communication skills.

The Grid Interactive Controls Research Group (GICR) in the Electrification and Energy Infrastructure Division (EEID) within the Energy Science and Technology Directorate (ESTD) at Oak Ridge National Laboratory (ORNL) is seeking a Postdoctoral Research Associate. The Grid Interactive Controls group specializes in pioneering innovations at the edge of today’s power grid, concentrating on fortifying grid security, enhancing reliability, bolstering resilience and advancing decarbonization. Our primary focus lies in the comprehensive ‘Everything-to-Grid’ (X2G) strategies, developing ground breaking solutions in grid-edge integration and control. Our commitment revolves around seamlessly incorporating emerging distributed energy resources, including demand response emerging at the grid edge, providing essential services crucial to its reliable operation. Employing a diverse range of disciplines such as control theory, optimization, economics, game theory, data analytics, and machine learning, the Grid Interactive Controls group delves deeply into understanding intricate grid-edge operations. Researchers are dedicated to laying the groundwork for optimal X2G integration and utilization. Group initiatives encompass innovative sensor technologies, advanced modeling techniques, and precise control mechanisms specifically designed for the grid edge. Research promotes grid-interactive efficient buildings as pivotal components in advancing building-to-grid integration, amplifying their role in electrification of heating and ultimately shaping the future decarbonized grid.

Selection will be based on qualifications, relevant experience, skills, and education. The successful candidate should be highly self-motivated and independent in conducting research under general guidance and is expected to prepare manuscripts for scientific publication and present the work to sponsors and at conferences.  As part of our research team, the candidate will be responsible for conducting, coordinating, and reporting complex research assignments related to buildings, specifically: 1) system modeling and optimization with applications to building-to-grid integration, and 2) software development to support the deployment of advanced control strategies in real building systems.
