Date: Aug 26, 2023

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 11244 

Overview: 

We are seeking a Postdoctoral Research Associate who will focus on efforts to establish the processes by which chemical reactivity results in fracture and grain boundary opening and closing.  This position resides in the Geochemistry and Interfacial Sciences Group in the Chemical Transformations Section, Chemical Sciences Division (CSD), Physical Sciences Directorate (PSD), at Oak Ridge National Laboratory (ORNL).  

As part of our team, you will work with a team of scientists in the Geochemistry and Interfacial Sciences Group to perform experiments to understand the effects of chemomechanical feedback mechanisms including crystallization pressure and localized stress/strain that result in fracture and grain boundary opening and closing. Experiments are expected to involve high pressure/temperature systems, mineral synthesis, and analyses using a variety of neutron and X-ray scattering techniques, coupled with other approaches as needed.

As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an extraordinary 80-year history of solving the nation’s biggest problems. With a dedicated and creative staff of over 6,000 people, ORNL’s decadal vision for diversity, equity, inclusion, and accessibility (DEIA) is to cultivate an environment and practices that foster diversity in ideas and in the people across the organization, as well as to ensure ORNL is recognized as a workplace of choice. These elements are critical for enabling the execution of ORNL’s broader mission to accelerate scientific discoveries and their translation into energy, environment, and security solutions for the nation. 

Major Duties/Responsibilities: 

  • Collaborate with ORNL researchers on the design and execution of experiments in nucleation and chemomechanical effects
  • Responsible for presenting research results at international meetings and publishing scientific results in peer-reviewed journals in a timely manner
  • Ensure compliance with environment, safety, health, and quality program requirements
  • Maintain strong commitment to the implementation and perpetuation of values and ethics
  • Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote diversity, equity, inclusion, and accessibility by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Basic Qualifications:

  • A PhD in Physical Sciences or Chemical Engineering, Geochemistry, Chemistry, Materials Science, or a related field completed within the last 5 years
  • Experience in the design and implementation of geochemical experiments

Preferred Qualifications:

  • Expertise in any of the following: neutron, X-ray, and light scattering (particularly (U)SANS, SAXS, INS, QENS, SALS, neutron diffraction and total scattering)
  • Experience in experimental work, especially in high pressure/temperature aqueous systems
  • Willing to enthusiastically learn new techniques and apply them to problems of geochemical significance
  • A record of collaboration with computational chemists, especially comparison of models to observations of mineral surfaces, stress/strain, and fluid transport
  • An excellent record of productive and creative research demonstrated by publications in peer-reviewed journals
  • The ability to work on and complete multiple tasks in a limited amount of time and to independently set priorities to accomplish multiple tasks to meet deadlines.
  • Excellent written and oral communication skills
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs
  • Excellent written and oral communication skills
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory 
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs
