Data Science/ML Postdoctoral Researcher

Idaho National Laboratory is hiring a Data Science/Machine Learning Postdoctoral Researcher to work in our Energy Storage Research & Analysis department. Our team works a 9x80 schedule located out of our Idaho Falls facility with every other Friday off.

This Postdoctoral Researcher will focus on expanding and developing data-driven and/or physics-based diagnostic, prognostic, and life prediction methods for Lithium-ion Batteries (LiB) using a rich collection of electrode and cell-level data. You will report to the project investigator.

The ideal candidate has a strong background in Python, with additional experience in C++ and MATLAB, particularly in Object-Oriented Programming (OOP). Proficiency in TensorFlow and PyTorch for AI model development is necessary . You should understand time series modeling and AI architectures such as LSTM, GRU, and CNNs, and be able to explore and customize AI models to solve specific problems. Experience processing large datasets, including filtering, cleaning, and anomaly detection, is required. A thorough understanding of Bayesian models like Gaussian Processes and Gaussian Mixture Models is necessary.

You should have a strong statistical foundation with experience in generative models such as Variational Autoencoders and GANs. Knowledge of diffusion models for degradation modeling is highly desirable. Additionally, understanding lithium-ion systems, with relevant published work, is preferred. Familiarity with machine learning basics, including stochastic gradient descent, activation functions, loss functions, optimizers, and Physics-Informed Neural Networks (PINNs), is also required.

The position entails writing scientific manuscripts for journal publication, and presentation of research results at national and international conferences and meetings.

Minimum Requirements:

• PhD in Computer Science with an emphasis in Machine Learning, Electrical Engineering, Chemistry, Chemical Engineering, Mechanical Engineering or related disciplines.
• PhD requirements must be completed by commencement of appointment and within the previous 5 years.
• Expertise in utilizing Data Science/ML methodologies for detecting and identifying failure modes.
• Proficient in Machine Learning technologies, with a focus on developing Transfer Learning techniques and Bayesian Design Optimization such as Gaussian Processes and Gaussian Mixture Models. This also includes stochastic gradient descent, activation functions, loss functions, optimizers, and Physics-Informed Neural Networks (PINNs).
• Proficiency in Python programming.
• Building history of publishing research articles in respected peer-reviewed journals in the position's research area.
• Adept in formulating research plans, designing experiments, data analysis, and the formulation of conclusions and manuscript writing.

Desired Requirements:

• Experience working with lithium ion batteries and understanding lithium-ion systems, with relevant published work.
• Knowledge of diffusion models for degradation modeling

Job Information:

• The target salary for this position is $101,196.00 Annually. At Idaho National Laboratory compensation decisions are determined using factors such as education, relevant experience, and other credentials.
