Job Description

We an opening for a Postdoctoral Research Staff Member in machine learning approaches for corrosion modeling in actinide metal and metal-oxide materials. The primary research thrust of this position involves the creation of machine-learning based potentials for molecular simulation to identify and understand chemical reaction mechanisms of surface adsorbed atmospheric gases. You will help create a multi-scale simulation approach that leverages a combination of quantum calculations, molecular dynamics, and coarse-grained simulations. The technical goals of this work are to utilize novel computational models to help interpret long timescale reaction dynamics observed in experiments on these systems. This position is in the Materials Science Division.

In this role you will

• Perform quantum calculations and machine-learning based model development of high-Z materials and their surface chemistry.

• Calculate of quantum nuclear vibrational effects in bulk and surface properties.

• Document research; publish papers in peer-reviewed journals, and present results within the DOE community and at conferences.

• Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.

• Collaborate with scientists in a multidisciplinary team environment to accomplish research goals.

• Perform other duties as assigned.

Qualifications

• Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.

• PhD in Physics, Chemistry, Materials Science, or related field.

• Experience in first-principles simulation techniques of condensed phases.

• Experience in programming in C++, Fortran 95, or an equivalent high-level language. Knowledge of a scripting language is a plus.

• Ability to develop independent research projects through publication of peer-reviewed literature.

• 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

• Experience in simulations of oxidation, hydriding, or corrosion processes in metallic alloys.

• Experience with the application of machine learning methods to accelerate materials research.

• Experience performing large-scale simulations on high-performance computing environments.
