Job Information

Pacific Northwest National Laboratory Post Doctorate RA - Subsurface Flow and Heat Transfer Modeling in Global Earth System Model in RICHLAND, Washington

Organization and Job ID

Job ID: 311994

Directorate: Earth & Biological Sciences

Division: Atmospheric Sciences & Global Change

Group: Earth System Modeling

Job Description

The Land Surface Modeling team within the Atmospheric Sciences & Global Change Division at the Pacific Northwest National Laboratory is seeking applications for a Post-Doctoral Research Associate position to conduct innovative research in developing a state-of-the-art subsurface flow and heat transfer model for DOE’s hyperresolution (1km) E3SM Land Model (ELM). The successful candidate will collaborate with a team of Earth scientists, applied mathematicians, and computer scientists on a DOE funded SciDAC project aimed at developing an open-source, multi-physics terrestrial dynamical core (TDycore) for mechanistically representing 3D subsurface hydrology and thermal processes in ELM . The research associate will use DOE’s current and upcoming heterogeneous computing architectures to study the scalability of the TDycore and participate in the development of subgrid parameterization for subsurface processes.

Through their research, the associate will develop an internal and external network of collaborators and project partners and participate in professional societies at the regional and national level. The associate is expected demonstrate commitment to data quality and accuracy, strong written and oral communication skills, as evidenced by high-impact peer-reviewed publications and conference presentations and be able to work independently and in a team setting. The applicant must demonstrate a strong ethic of service to the scientific community and a commitment to both scientific excellence and national impact on developing transformative science and technology solutions relevant to our nation’s energy security and prosperity. Finally, the position requires that the associate complies with PNNL policies regarding environmental health and safety, waste management, and protection of intellectual property.

The initial appointment is for one year with the possibility of a second-year renewal subject to satisfactory performance.

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

The candidate must have experience in applying and numerical models to study subsurface terrestrial processes

Preferred qualifications include:

  • Experience simulating subsurface flow and heat transfer processes at watershed, regional or global scales

  • Demonstrated proficiency with object-oriented programming using modern Fortran or C/C++ Experience using or developing models using Portable, Extensible Toolkit for Scientific Computation (PETSc)

  • Experience coupling 3D subsurface models with regional- or global-scale land surface models

  • Experience developing open-source software using continuous integration (distributed version control, automated testing, etc.)

Candidates must have received a PhD in computational science, engineering, geosciences, or applied mathematics
