 High Performace Particle Numerical Modeling Postdoctoral Research Associate - (11348) Description   Job Information Job Title: High Performance Particle Numerical Postdoctoral Research Associate
Org:  Materials Science & Engineering
Work Location:  Idaho Falls, Idaho, United States (Town)



Mission/Vision Statement Empowering the Nation's Energy Future Mission: Discover, demonstrate and secure innovative nuclear energy solutions, other clean energy options and critical infrastructure. Vision: INL will change the world's energy future and secure our critical infrastructure.


Responsibilities Idaho National Laboratory (INL) is seeking applicants for a High Performance Particle Numerical Postdoctoral Research Associate.  A postdoctoral researcher position in high performance computational particle-based numerical modeling will be available starting from October 2017 in the Energy and Environment Science & Technology (EES&T) Directorate at INL. The EES&T modeling & simulation (M&S) group is looking for highly motivated applicants with a strong background and experience in particle-based computational methods and high performance computing (HPC). The research and development (R&D) work currently going on in the M&S group includes subsurface science, waste management and processing, bioenergy, catalysis, batteries, and nuclear science and engineering.

The postdoc researcher in this position is expected to:

• Research and develop advanced parallel computing schemes for particle-based mesoscale numerical methods, such as discrete element methods (DEM), smoothed particle hydrodynamics (SPH), and dissipative particle dynamics (DPD) to achieve sustainable scalability on parallel computing architectures ranging from existing high performance computing (HPC) clusters, to U.S. Department of Energy’s (DOE) next-generation leadership-class supercomputers at DOE national laboratories. DEM will be prioritized during the initial phase of R&D.
• Research and develop innovative modeling methods for supporting INL mission-critical research areas, such as recovery of unconventional fossil fuels from nanoporous tight shales, thermal-hydraulic fracturing of ultra-low-permeability crystalline rocks, flow and transport of fluidized biomass feedstock, and transport of electrolyte and ions in nanoporous electrodes.
• Develop automated verification & validation (V&V) test problem suites for software quality assurance, and prepare technical documentation for all code development and simulation problems.
• Be willing and proactive to expand knowledge in domains beyond one’s past experience.
• Collaborate closely with group members in the M&S group, and be willing to actively communicate and collaborate with other scientists in relevant science/engineering majors across the laboratory.
• Publish accomplished research work in high-impact-factor journals in a timely manner.
• Participate in proposal writing in response to funding opportunity announcements when necessary.
• Mentor undergraduate/graduate student interns when needed. Qualifications • PhD requirements must be completed by commencement of appointment and within the previous 5 years 
• PhD in engineering, physical science, applied mathematics or comparable disciplines
• Demonstrated oral and published written communication skills.

Special Requirements and/or Training: 
· Strong background of code development in at least one particle-based numerical simulation method, e.g. molecular dynamics (MD), DEM, DPD, SPH, etc.
· Strong skills of developing parallel computing codes using MPI and/or OpenMP.
· Proficiency in C/C++ programming.
· Familiarity with the Linux/UNIX environment.
· Experience with at least one open-source particle simulation platform, e.g. LAMMPS, HOOMD-blue, GROMACS, etc.
· Strong skills of parallel computing runtime performance analysis and optimization.
· Experience with GPU programming.
· Experience with Python programming.
