Postdoctoral Research Associate in Computational Earth Sciences

Updated: about 12 hours ago
Location: Oak Ridge, TENNESSEE

Requisition Id 1001 


 

 

Overview:

The Computational Earth Sciences Group (CESG) and the Climate Change Science Institute (CCSI; https://ccsi.ornl.gov/ ) at the Oak Ridge National Laboratory (ORNL) are seeking a qualified postdoctoral candidate in the field of Computational Earth Sciences. ORNL’s CESG conducts world-class research and development in Earth system modeling, model-data integration, large scale data analytics and machine learning, and model benchmarking at the US Department of Energy’s (DOE’s) Leadership Class Computing Facilities (LCFs).

 


Major Duties/Responsibilities:
  • Conduct regional and global Earth system model (ESM) simulations, focusing on analyzing land-atmosphere and land ice-atmosphere interactions.
  • Collaborate with a diverse team of Earth system and computational scientists, both within the CESG and across DOE Labs and partner universities, to apply validation, uncertainty quantification, and machine learning methods aimed at enhancing predictive understanding of the Earth system.
  • Analyze model simulation results to understand land-atmosphere, land ice-atmosphere interactions, ice sheet responses and ecosystem responses to global change.
  • Work with the research community to develop validation analyses, and use machine learning methods to build effective surrogate models based on ESM simulations and to construct purely data-driven models based on available observation data.
  • Develop tools to run large-scale ESMs efficiently in ensemble mode on LCF machines, develop multi-fidelity approaches, and develop verification and validation procedures for these ensembles.
  • Publish research in peer-reviewed journals and present results at national and international conferences.

Preferred Qualifications:

  • Knowledge of uncertainty quantification and reduction methods and machine learning algorithms;
  • Familiarity with data file formats and conventions (e.g., CF, netCDF, HDF);
  • Experience with data manipulation and analysis packages (e.g., Python, R, NCL, NCO, Matlab);
  • Experience with the Linux operating system, LaTeX, Git, Python, and Fortran and/or C/C++;
  • Collaborative research capabilities as demonstrated by existing peer-reviewed publications and technical proposals;
  • Strongly motivated to perform and publish leading edge research;
  • Experience with high performance computing, advanced statistical and machine learning methods, and visual data analytics approaches;
  • Knowledge of terrestrial ecosystem processes, land-atmosphere interactions, land

ice-atmosphere interactions, and ice sheet processes and their representations in ESMs;

  • Excellent verbal and written communication skills.

 

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