Requisition Id 11663


The National Security Sciences Directorate at Oak Ridge National Laboratory leads scientific and technological breakthroughs to confront some of the nation’s most difficult security challenges. We develop interdisciplinary applications needed for the security of our nation today and target our vision on how these challenges may manifest themselves in a decade or more. Our research and development focuses on cybersecurity and cyber physical resiliency, data analytics, geospatial science and technology, nuclear nonproliferation, and high-performance computing for sensitive national security missions. We also enhance ORNL contributions to national security challenges by working closely with leading researchers at the lab in areas such as nuclear and chemical sciences and engineering, applied materials, advanced manufacturing, biosecurity, transportation, and computing. We are currently seeking a qualified data scientist with substantial experience in spatiotemporal data analytics to join our GeoAI group within the Geographic Data Science Section of Geospatial Science and Human Security Division. We are interested in candidates experienced in solving spatial and spatiotemporal challenges with demonstrated skill sets in managing, analyzing, visualizing, and publishing on R&D results. Examples of the data you will work with include but are not limited to georeferenced times series derived from longitudinal survey data (economics, census, sociocultural, etc.), network data (e.g., international trade, social media, transportation), remote sensing (earth observation systems, optical, multispectral, SAR, LiDAR, etc.), climate (earth observation, ground sensors, etc.). Analytics include ST data mining, change detection, trend clustering, graph networks, visualization, machine learning, and nowcasting. In this role, you will work with a team to develop theoretical and applied expertise to solve at scale problems across a range of application domains including climate change security, socio-economic security, transportation, population dynamics, built environment, and quality control at scale. The position requires strong skills in computer science, data science, machine learning, with experience in conceptualizing and developing prototype code and workflows.

Within the GeoAI group, you will have the opportunity to develop and publish on novel solutions to national and global problems using cutting edge spatial and spatiotemporal methods. You will be able define and grow your scientific brand at ORNL through your success in projects, laboratory presentations and networks, and through the cross-directorate interdisciplinary teaming. You will have an opportunity to grow your career with high external visibility by attending, presenting, and networking at peer reviewed conferences.

Major Duties and Responsibilities:

  • Contribute to interdisciplinary research teams solving spatial and spatiotemporal challenges at scale in data mining, machine learning, change detection, inferencing, nowcasting, uncertainty quantification, and quality control.
  • Contribute to the conceptualization and design of new algorithms for performing ST Analytics.

  • Experience programming in Python, R, or similar.
  • Experience working with spatio-temporal datasets especially georeferenced time series data.
  • Demonstrated experience designing and developing prototype code and workflows
  • Interpersonal skills with a demonstrated experience in successfully working in team environments.
  • Strong written and oral communication skills.

Preferred Qualifications:

  • A track record of peer reviewed publications in spatiotemporal applications
  • Experience working in a national laboratory engaged in defense and security applications.
  • Working knowledge or strong interest in Bayesian analysis and Causality
  • Strong drive to learn new topics and skills, to develop innovative products for our customers, and build new programs to expand our capability.

Special Requirement:

This position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program. This position requires the ability to obtain a DOE Clearance.

The National Security Sciences Directorate conducts research and development to confront some of the nation’s most difficult security challenges and adversaries.
