Applied Data Scientist - R&D Associate
Date: Oct 25, 2024
Location: Oak Ridge, TN, US, 37830
Company: Oak Ridge National Laboratory
Requisition Id 13639
Overview:
We are seeking an Applied Data Scientist to perform research and development of novel and advanced AI/ML algorithms. This R&D will support a broad user base with applications including: autonomous robotic control; AI-enhanced data retrieval and inference; multi-modal, networked detector systems; gamma spectroscopy; radiation imaging and 3D reconstruciton; data-mining; anomaly detection; and neuromorphic computing. This role resides in the Advanced Detection and Applied Data Science (ADADS) group, Nuclear Structure & Advanced Technologies Section, Physics Division, Physical Sciences Directorate, at Oak Ridge National Laboratory (ORNL).
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.
As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an extraordinary 80-year history of solving the nation’s biggest problems. We have a dedicated and creative staff of over 6,000 people! Our vision for diversity, equity, inclusion, and accessibility (DEIA) is to cultivate an environment and practices that foster diversity in ideas and in the people across the organization, as well as to ensure ORNL is recognized as a workplace of choice. These elements are critical for enabling the execution of ORNL’s broader mission to accelerate scientific discoveries and their translation into energy, environment, and security solutions for the nation.
Major Duties/Responsibilities:
- In this role, you will work with research staff within ADADS and throughout ORNL to develop and apply modern data science/machine learning techniques to a wide variety of subjects including nuclear material detection, nuclide identification, and radioactive materials localization capabilities to support nuclear security missions.
- The research involves development and testing of novel data analytics processes and specialized algorithms to improve measurement efficiency and reduce uncertainties.
- 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.
- You will also deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote diversity, equity, inclusion, and accessibility by fostering a respectful workplace – in how we treat one another, work together, and measure success.
Basic Qualifications:
- PhD in computer science, physics, statistics, engineering, chemistry, mathematics or a related field. A master’s degree in computer science, physics, statistics, engineering, chemistry, mathematics or a related field with a minimum of 3 years of experience in data science may also be considered.
- Demonstrated capabilities and experience in data science or data analytics
- Ability to obtain and maintain a clearance from the Department of Energy

- Reinforcement Learning (RL) and/or autonomous robotic control
- Computer vision (2D/3D object detection/segmentation; depth/pose estimation, image captioning/text extraction)
- Unsupervised/Semi-supervised learning and data mining techniques (clustering, embeddings, dimensionality reduction, anomaly detection)
- Physics informed machine learning
- Practical experience using ML models:
- Dataset curation and preprocessing
- Applications leveraging off-the-shelf ML models
- Fine-tuning pre-trained models for specific tasks
- Designing and training models, especially deep-learning models, from scratch
- ML-Ops experience (model deployment, model/code/dataset management)
- Familiarity with relevant technologies such as:
- Computer programming languages such as Python, JavaScript, C, C++, and R
- Machine learning libraries such as Pytorch, TensorFlow, Scikit-Learn, and OpenCV
- Interactive data visualization tools such as jupyter-widgets, D3, three.js, and/or plotly
- 3D game development software such as Unity including VR/AR packages
- Linux, Docker and Git
- Commitment to stay current with modern data analytics/machine learning trends
- A strong interest in problem solving and applying new skills and methods
- Excellent human relation and oral and written communication skills and a demonstrated ability to work in a team-oriented environment with a broad range of domestic or international collaborators
- Ability to work both independently, with minimal supervision, or as an effective member of an agile development team
Special Requirements:
