At PNNL, our core capabilities are divided among major departments that we refer to as Directorates within the Lab, focused on a specific area of scientific research or other function, with its own leadership team and dedicated budget.

Our Science & Technology directorates include National Security, Earth and Biological Sciences, Physical and Computational Sciences, and Energy and Environment. In addition, we have an Environmental Molecular Sciences Laboratory, a Department of Energy, Office of Science user facility housed on the PNNL campus.

The National Security Directorate (NSD) drives science-based, mission-focused solutions to take on complex, real-world threats to our nation and the world.

The Nuclear, Chemical, and Biological Technologies Division, within the National Security Directorate, works across fundamental science, research and development, and operations to counter emerging national security threats. We focus on discovering signatures and understanding threats by creating materials, methods, and technologies to detect and analyze them. Our researchers deliver the solutions necessary for addressing complex mission challenges, such as explosives detection, biological threat detection, chemical and nuclear forensics, and special nuclear materials.  

• Perform hands-on R&D in radiation detection technologies; measure, analyze, and characterize radiation signatures supporting interdiction, nonproliferation, treaty verification, safeguards, and nuclear incident response.
• Plan and execute laboratory and field tests/experiments, including test setup, test plans, schedules, risk assessments, and required documentation.
• Analyze radiation detection datasets; conduct technical assessments, performance evaluations, and failure/equipment analyses; participate in peer reviews.
• Develop, review, and provide SME input on operating procedures, documentation, and best practices for radiation detection systems and missions (including ConOps, T&E approaches, and guidance).
• Provide technical input on design, hardware integration, troubleshooting, and maintenance of radiation detection systems.
• Conduct modeling and simulation using physics-based tools; interpret and communicate simulation outputs to assess signatures/fields from radioactive materials.
• Contribute to emerging standards, regulations, and stakeholder requirements related to radiation detection and radioactive materials.
• Prepare and deliver project outputs (data packages, reports, briefings, and hardware samples as needed).
• Lead/coordinate project execution: define scope and milestones, develop integrated work plans, track progress against deliverables, and manage action items to closure.
• Manage resources to meet project objectives: coordinate staff assignments, lab/field logistics, equipment procurement/calibration, and vendor/subcontractor support as needed.
• Support budget and reporting activities: develop cost estimates, monitor burn rates, and provide status updates to sponsors/stakeholders.
• Facilitate technical and programmatic reviews: organize readiness reviews, capture decisions, and maintain project documentation/configuration control.
• Identify and manage project risks/issues: implement mitigations, ensure safety/compliance requirements are met, and support corrective/preventive actions.
• Engage stakeholders and partners: align requirements, manage expectations, and communicate timelines, constraints, and results.
• Mentor students and early-career staff; contribute effectively within collaborative, multi-disciplinary teams.
