The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor (HFIR), the United States' highest flux reactor based neutron source, and the Spallation Neutron Source (SNS), the world's most intense pulsed accelerator based neutron source. Together these facilities operate 30 instruments for neutron scattering research, each year carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical sciences. HFIR also provides unique facilities for isotope production and neutron irradiation. To learn more about Neutron Sciences at ORNL go to: http://neutrons.ornl.gov. Oak Ridge National Laboratory is also a leader in computational and computer science, with unique strengths in high-performance computing and data analytics with applications to the physical and biological sciences.
We are seeking a postdoctoral research associate who will focus on signal processing, statistical analysis, probabilistic theory and machine learning with emphasis on diagnostics and prognostics applications. This position resides in the Accelerator Science and Technology Section in the Research Accelerator Division, Neutron Sciences Diretorate at Oak Ridge National Laboratory (ORNL).
As part of our research team, you will work with accelerator and target systems specialists and machine learning experts to develop, integrate and apply machine learning methods to improve performance of the SNS 1.4 MW accelerator and target systems.
Develop, implement and apply new machine-learning (ML) and statistical methods techniques to sensor and component health monitoring, anomaly detection and fault isolation
Develop and apply both first-principles-based and data-driven techniques to solving complex engineering problems
Perform uncertainty quantification and uncertainty propagation analyses
PhD in nuclear, electrical engineering, mechanical, computer engineering, or engineering physics, computational science or a related field within the past 5 years.
Experience with open-source machine-learning tools, such as TensorFlow, pyTorch or Keras
Experience with applying and deploying recent machine-learning methods for solving complex engineering problems, including diagnostics and prognostics of complex engineered systems
Experience in physics-informed machine learning for analysis of physical systems
Experience with uncertainty quantification methods and application of those methods in complex systems
Experience working in Linux environments on large high-performance cluster computing architectures
Demonstrated experience in statistical methods and machine-learning methods, with a specific application to time-series datasets from multiple sensors
Strong understanding of underlying mathematics of signal processing, filtering and machine learning to unfold unique signatures in typical noisy time-series data
Demonstrated results-oriented problem-solving skills, and a willingness to apply those skills to a variety of engineering problems
Excellent communication skills (verbal, presentation and scientific writing) that enable effective interaction with technical peers, program managers, and sponsors
Strong scholarly and publication record that demonstrates independence and initiative taking
Ability to work independently and in a team environment, thoroughly document work performed
