Postdoctoral Research Associate - Atomic-Scale Simulation

Requisition Id 15656 

 

Overview:

The Geochemistry and Interfacial Sciences Group in the Chemical Sciences Division (CSD) at Oak Ridge National Laboratory (ORNL) invites outstanding applications for a post-doctoral research associate to simulate amorphous materials and crystallization reactions using atomic-scale simulations. As a post-doc, you will utilize high performance computing and rare event methods to work with a team of scientists in CSD to model chemical reactions important to determine the longevity of amorphous materials. That mechanistic information will be incorporated into process-based models that can describe rates and locales of precipitation.

 

Major Duties/Responsibilities:

• Conduct independent research using atomic-scale simulation with rare event methods to understand hydroxylation and carbonation reactions in aqueous solutions, amorphous materials and at mineral-water interfaces.
• Collaborate with ORNL researchers on the design and execution of experiments to measure crystallization reactions.
• Present and report research results and publish scientific findings in peer-reviewed journals in a timely manner.
• Ensure compliance with environmental, safety, health and quality program requirements.
• Maintain strong commitment to the implementation and perpetuation of values and ethics.
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success.

 

Basic Qualifications:

• A PhD in Physical Sciences, such as Geochemistry, Chemistry, Geology, Materials Science, or related disciplines completed within the last 5 years.
• Strong background in atomic-scale simulation.

 

Preferred Qualifications:

• Experience using CMD, AIMD, DFTB, MD with rare event methods (metadynamics, umbrella sampling, replica exchange, etc.).
• Experience with simulating reactions, such as ligand exchanges and crystallization reactions, in aqueous solutions and at solid-water interfaces.
• Excellent record of productive and creative research demonstrated by publications in peer-reviewed journals.
• Excellent written and oral communication skills.
• Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
• Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.

 

Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment.

 

The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding.

 

Reference Letters:

Please submit three letters of reference when applying for this position. You can upload these directly to your application or have them sent to postdocrecruitment@ornl.gov with the position title and number referenced in the subject line.
