[lammps-users] Postdoc Opening at Idaho National Laboratory

From: Yidong Xia <yidongxia@...24...>
Date: Thu, 24 Aug 2017 16:09:31 -0600

Job Title: Postdoctoral Researcher – High Performance Computational Particle Multiphysics
Employer: Idaho National Laboratory
Location: Idaho Falls, Idaho, United States
Closing Date: Until filled
Contact: Yidong Xia (Yidong.Xia at
(International applicants are welcome. U.S. permanent residency or citizenship is not required)

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 Idaho National Laboratory (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 initial appointment will be for one year, and it may be extended to a maximum of 3 years based on satisfactory progress. To apply, please send your CV/resume with a cover letter, a list of publications, and contact information for at least 3 references to Dr. Yidong Xia (Yidong.Xia at with the email subject “Postdoc Position Application”. Applicants must be willing to participate in a telephone interview and on-site interview upon request. The salary is competitive with an excellent benefits package.

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.

Required Qualifications:
A Ph.D. degree in engineering, physical science or applied mathematics.
Strong interest and self-motivation to perform cutting-edge research, conquer frontier research challenges, and publish high-impact papers.
Strong background of code development in at least one type of the particle-based numerical simulation methods, 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.

Preferred Qualifications:
Experience with open-source particle simulators, e.g. LAMMPS, HOOMD-blue, GROMACS, etc.
Strong skills of parallel computing runtime performance analysis and optimization.
Experience with GPU programming with CUDA and/or OpenACC directives.
Experience with Python programming.
