Post Doc Research Associate - Geochemistry

22.10.2018 - Pacific Northwest National Laboratory (PNNL), Richland, WA

The Subsurface Science & Technology Group at the Pacific Northwest National Laboratory is seeking a highly motivated individual with a strong ethic of service to the scientific community and a commitment to both scientific excellence and national impact on critical scientific and technical problems facing the U.S. The candidate is expected to support laboratory-based research on the processes and reactions that affect and/or control the mobilization and immobilization of contaminants in heterogeneous media.

Job Description
Some key aspects include the use of macroscopic methods (batch and column systems) and microscopic and spectroscopic techniques to (i) measure rates, (ii) determine mechanisms, (iii) develop an understanding of coupled reactions, e.g. adsorption/desorption, dissolution/precipitation, substitution, and electron transfer, and (iv) identify changes in the chemical, mineralogical and physical properties of target media at different temporal and spatial scales. The candidate is also expected to use an iterative approach of geochemical modeling and experimentation to test the hypotheses and determine predictive model parameters.

The candidate will support research efforts as part of a multi-disciplinary scientific team contributing to ongoing technical activities, as well as contribute to and develop proposals for future research funding. Candidate must be familiar with standard chemical laboratory operating procedures and standard analytical techniques. Applicants must be willing to learn and employ safe techniques for handling hazardous materials. Candidate must be able to work with colleagues in a laboratory environment on the implementation of experimental procedures.

The candidate will be required to maintain laboratory notebooks and is expected to have sufficient time management skills to balance the demands of several concurrently operating projects. The ideal candidate for this position will be a well-organized, self-starter with meticulous attention to detail. In addition, the candidate will have strong data interpretation skills, excellent written and oral communication skills, and will be expected to maintain a regular publication record.

Minimum Qualifications
Candidates must have received a PhD within the past five years (60 months) or within the next 8 months from an accredited college or university.

Preferred Qualifications

  1. Candidate must have a Ph.D in chemistry, materials science, geochemistry, radiochemistry, or performance testing of engineered waste forms.
  2. The incumbent must have experience working in a wet-chemistry laboratory around potentially hazardous acids, bases, and materials. Familiarity with macroscopic methods and common geochemical characterization techniques (e.g., SEM, TEM, XRD, XANES/EXAFS, XPS) is preferred.
  3. Candidate is expected to be proficient with standard office software, such as Microsoft Excel and Word.
  4. Excellent verbal and written communication skills are also required, and must be demonstrated via a strong publication record in peer-reviewed journals.
  5. 3.5 GPA or higher is preferred
