Job Description

We have an opening for a Postdoctoral Researcher in the field of advanced large-scale atomistic materials modeling.  You will apply expertise at the intersection of materials science and data science to advance uncertainty-aware atomistic simulations of dynamic processes in materials. The successful candidate will plan, execute, and interpret very-large scale simulations on advanced high-performance computers and contribute to quantification of uncertainty in these models. This position is in the Quantum Simulations Group of the Materials Science Division.

In this role you will 

  • Contribute to a multidisciplinary team to advance methodologies for and applications of accurate, error-quantified atomistic materials simulations.
  • Contribute to evaluation of error-quantified materials property predictions using large-scale molecular dynamics simulations.
  • Develop, analyze, and/or apply models to quantify uncertainty in large-scale molecular dynamics simulations.
  • Maintain an awareness of technical literature in assigned areas.
  • Publish research results in external peer-reviewed scientific journals and participate in international conferences.
  • Present formal and informal overview of research progress at weekly meetings.
  • Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally.
  • Perform other duties as assigned.

Qualifications

  • PhD in Material Science, Theoretical Chemistry, Applied Mathematics, Physics, or a related field.
  • Experience in atomistic modeling of materials using molecular dynamics simulations, especially of solid-state dynamic processes and/or reacting molecular systems.
  • Knowledge in the one or more of the following additional areas:  computational electronic structure, interatomic potential development, machine learning/data science methodologies, massively-parallel computing, high-energy density or high-pressure science, visualization.
  • Experience with very-large scale (100M+ atoms) molecular dynamics simulations.
  • Experience authoring technical and scientific reports, delivering scientific presentations, and developing independent research projects through publication of peer-reviewed literature.
  • Ability to work independently on technical tasks, influence technical objectives, to provide in depth analysis, and develop unique technical solutions.
  • Proficient verbal and written communication skills as reflected in effective presentations at seminars, meetings and/or teaching lectures.
  • Initiative and interpersonal skills with desire and ability to work in a collaborative, multidisciplinary team environment.

Qualifications We Desire

  • Machine learning / data science applied to interatomic potential development and analysis.
  • Experience with electronic structure-based (ab initio) atomistic modeling methods, include density functional theory, quantum Monte Carlo, and/or quantum chemical methods.
  • Experience with active learning and/or interpretability of machine learned data representations, including neural networks, Gaussian process models, and other constructs.
  • Experience with parallel programming tools and software development for large-scale heterogeneous computers, including GPUs.

Additional Information

All your information will be kept confidential according to EEO guidelines.

Position Information

This is a Postdoctoral appointment with the possibility of extension to a maximum of three years, open to those who have been awarded a PhD at time of hire date.
