Postdoctoral Research Associate - Advanced Computational Microstructural Modeling

Overview: 
Oak Ridge National Laboratory is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security.
 
We are seeking a Postdoctoral Research Associate who will support the Microstructural Evolution Modeling in the Materials Science and Technology Division (MSTD), Physical Sciences Directorate (PSD) at Oak Ridge National Laboratory (ORNL).  
 
This position will emphasize application of advanced computational microstructural modeling to understand phase stability and phase transformations during solidification and heat treatment in multicomponent structural materials. This position will also seek development of new models or approaches to bridge the gap between process modeling and microstructural modeling, and extend the existing modeling capabilities for conventional casting and heat treatment to additive manufacturing that is far from equilibrium. This position requires hands-on experiences on microstructural characterization. This work will be performed in interdisciplinary teams of computational and experimental researchers with tasks driven by project needs. Projects may address new alloys for additive manufacturing, high-temperature refractory alloys, gradient materials, and high entropy alloys.
 
Major Duties/Responsibilities: 
  • Coupling microstructural modeling with process modeling to understand microstructural evolution under various processing conditions
  • Perform microstructural characterization including SEM, TEM, XRD to support computational approaches to materials design
  • Work with members of dynamic research groups to develop theoretical approaches to support the development of next generation high-temperature materials for harsh environments
  • Responsible for presenting and reporting research and publishing scientific results in peer-reviewed journals in a timely manner
  • Ensure compliance with environment, safety, health and quality program requirements
  • Maintain strong dedication to the implementation and perpetuation of values and ethics
 
Basic Qualifications:
  • A PhD in Metallurgy, Materials Science & Engineering, Physics, Chemistry or a related field completed within the last 5 years
  • Strong background in microstructural modeling such as thermodynamics and kinetics modeling on phase stability and phase transformations
  • Expertise in using software (e.g., Thermo-Calc, DICTRA, PANDAT, FactSage)
  • Experience in microstructural characterization techniques (SEM, TEM, XRD)
  • A record of productive and creative research demonstrated by publications in peer-reviewed journals
 
Preferred Qualifications:
  • Experience in phase field and first-principles atomistic modeling approaches
  • Experience in programing using Matlab, Python, R program, OriginLab
  • 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
