We are seeking a Postdoctoral Research Associate to work a part of our Computational Astrophysics team. In this role, you will focus on state-of-the-art simulations for core-collapse supernovae, both analyzing the results of current simulations and developing the next-generation of simulation code and analysis tools. You will work alongside a dedicated team of researchers, both at Oak Ridge National Laboratory (ORNL) and as part of the multi-institutional CHIMERA team, and have the opportunity to share your results with the scientific community. This position resides in the Theoretical Physics Group of the Physics Division, Physical Sciences Directorate (PSD) at Oak Ridge National Laboratory (ORNL) and is part of the Towards Exascale Astrophysics of Mergers and Supernovae (TEAMS) project supported by the DOE Scientific Discovery through Advanced Computing (SciDAC) program.
As part of our research team, you will be responsible for running and analyzing state-of-the-art models of core-collapse supernovae (CCSNe) using the CHIMERA and FLASH5 codes. CHIMERA is a multi-physics code built specifically for multi-dimensional simulation of CCSNe. It combines separate codes for hydrodynamics and gravity; neutrino transport and opacities; and nuclear equation of state and reaction network. The models to be run will address key questions in the physics of CCSNe, for example, what is the range of stars for which successful CCSNe occur and what is the contribution of CCSNe to Galactic Chemical Evolution. In addition, you will contribute to the development of FLASH5, our next generation code for CCSNe and other astrophysical problems. FLASH5 is being built as a best-of-breed code from the existing CASTRO and FLASH codebases coupled to the AMReX package and a new ORNL-developed neutrino-transport module (development of FLASH5 is supported by the DoE Exascale Computing Project). Among your responsibilities will be porting of the CHIMERA analysis toolchain to FLASH5.
Perform state of the art simulations of core-collapse supernovae
Bring the CHIMERA analysis toolkit to bear on FLASH5 simulations
Assist with the development of FLASH5
Present and report research results and publish scientific results in peer-reviewed journals in a timely manner
Ensure compliance with environment, safety, health and quality program requirements
Maintain strong dedication to the implementation and perpetuation of values and ethics
A PhD in Physics, Astronomy, or a related discipline completed within the last five years
Experience in Nuclear or Stellar Astrophysics
Experience with High Performance Computing and/or programming for massively parallel computers.
An excellent record of productive and creative research as proven by publications in peer-reviewed journals and letters of reference from active practitioners in the field
Excellent written and oral communication skills and the ability to communicate in English to an international scientific audience
Motivated self-starter with the ability to work independently and to participate creatively in collaborative and frequently interacting teams of researchers
Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever-changing needs
Experience with MPI, OpenMP, parallel I/O (including HDF5), CUDA and/or OpenACC, FORTRAN, Python
