Job Description

We have an opening for a Postdoctoral Research Staff Member to contribute to fundamental R&D in machine learning and statistical methods in support of a new project on “Terraforming Soil”.  This interdisciplinary project aims to develop agricultural solutions for climate change mitigation.  In this role you will develop new multi-fidelity representation learning models to analyze large collections of soil spectra, infer important chemical markers, and account for both epistemic and aleatoric uncertainties in the process. This position will be in the Machine Intelligence Group in the Center for Applied Scientific Computing (CASC) Division within the LLNL Computing Directorate, in collaboration with the Physical and Life Sciences Directorate.

You will 

  • Research, design, implement, and apply advanced machine learning methods for multiple applications in a collaborative scientific environment.

  • Actively participate with project scientists and engineers in defining, planning, and formulating experimental, modeling, and simulation efforts for complex problems stemming from national security applications.

  • Propose and implement advanced analysis methodologies, collect and analyze data, and document results in technical reports and peer-reviewed publications.

  • Contribute to grant proposals and collaborate with others in a multidisciplinary team environment, including academic and industrial partners, to accomplish research goals.

  • Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internal and external to the Laboratory.

  • Perform other duties as assigned.


  • Recent Ph.D. in Machine Learning, Statistics, Computer Science, Mathematics or a related field.

  • Demonstrated ability and desire to obtain substantial domain knowledge in fields of application in order to communicate effectively with subject matter experts, and to identify novel, impactful applications of machine learning.

  • Experience developing, implementing and applying advanced statistical or machine learning models and algorithms using modern software libraries such as PyTorch, TensorFlow, or similar as evidence through medium to large scale deep learning models and experiments.

  • Demonstrated research productivity, as documented by publications, reports, presentations, and/or open-source software in relevant venues (NeurIPS, ICML, ICLR, CVPR, AAAI, AISTATS, UAI, KDD, JMLR, Nature etc.)

  • Experience with scientific programming in the Python ecosystem as evidence through software artifacts, such as deep learning models, workflows, simulations, or similar

  • Experience with one or more of the following areas of deep learning: representation learning, uncertainty quantification, physics-constrained ML, Bayesian optimization, reinforcement learning, multimodal models, generative models.

Qualifications We Desire

  • Experience with high-performance computing, GPU programming, parallel programming, cloud computing, and/or related methods including running numerical simulations of complex workflow

  • Demonstrated technical leadership in fields related to machine learning, such as mentorship or managing teams.

  • Experience or interest in environmental science, climate change mitigation, soil chemistry or infrared spectroscopy
