Applied Data Scientist - Staff Member

ADADS draws from fundamental physics to develop technologies and processes that support the design, development, and deployment of high-sensitivity detection systems for measuring radiation and other physics phenomenologies. The group focuses on the development and evaluation of novel and advanced radiation detector and non-destructive evaluation concepts for basic science, nonproliferation, national security, and intelligence organizations. The ADADS group performs the research and technology development to evolve these advanced concepts from conception to demonstration or deployment with particular emphasis on sensitivity and specificity in actual field operations, including use of radiation transport codes to model these systems and analysis codes to isolate signals of interest., In this role, you will work with and support research staff within ADADS and throughout ORNL to develop and apply modern data science/machine learning techniques to a wide variety of subjects including the characterization of nuclear material and nuclear facility operations, as well as more fundamental physics research. The research involves development and testing of novel data analytics processes and specialized methods to improve measurement fidelity and reduce uncertainties in models used for real-world decisions.Results will be documented by publication in high impact papers, journals, conference papers and technical reports. The work will involve collaboration in a team environment performing project work and developing research proposals.
