Computational Research Scientist in the Area of Low Temperature Low Pressure Processing Plasma

Job description

Overview


The Princeton Plasma Physics Laboratory (PPPL) is seeking to appoint a Computational Scientist to contribute to the advancement of modeling capabilities and physics research pertaining to low-temperature plasmas and associated technologies.

The primary responsibility of this position involves conducting and facilitating computational modeling of authentic low-temperature plasma devices, particularly those operating at low pressure, for the purposes of scientific discovery and engineering design.

The successful candidate will achieve this objective through the application of high-performance computing (HPC) best practices, advanced mathematical research into novel algorithms, and the utilization of machine learning techniques for code acceleration and the development of reduced-order surrogate models.

This will require working with and maintaining the LTP-PIC software, a particle-in-cell (PIC) software package developed at PPPL for these purposes.

The candidate should have strong familiarity with compiler level languages, accelerated computing (preferably with OpenMP or OpenACC) and distributed computing (MPI).

A thorough understanding of the particle-in-cell algorithm, its inherent limitations, and potential avenues for performance enhancement is also required.

Furthermore, the candidate should demonstrate substantial practical knowledge of low-pressure capacitively and inductively coupled discharges employed in plasma processing, coupled with a proven track record of kinetic modeling of such discharges.

The candidate should be familiar with machine-learning principles for science, including generative A.I. and surrogate models, especially of convolutional and recurrent neural networks.

Familiarity with Python, NumPy and PyTorch will be essential for this position.

The computational tools developed will be instrumental in studies of capacitively-coupled plasmas and partially magnetized plasma sources, as well as the fundamental understanding of anomalous transport and plasma turbulence within these devices.

The software will also be disseminated to the broader academic and industrial communities, necessitating strong interpersonal and communication skills to cultivate these relationships.

Finally, this role will encompass the conceptualization and preparation of novel proposal ideas to secure funding for future research projects.
A U.S. Department of Energy National Laboratory managed by Princeton University, the Princeton Plasma Physics Laboratory (PPPL) is tackling the world’s toughest science and technology challenges using plasma, the fourth state of matter.

With more than 70 years of history, PPPL is a leader in the science and engineering behind the development of fusion energy, a potentially limitless energy source.

PPPL is also using its expertise to advance research in the areas of microelectronics, quantum sensors and devices, and sustainability sciences.

Whether it be through science, engineering, technology or professional services, every team member has an opportunity to contribute to our mission and vision.
