Computational Challenges and Optimization in Kinetic Plasma Physics

February 19 — 22, 2024

Description

Back to top

Nuclear fusion holds immense promise as a source of clean, safe, and sustainable energy.  Critical to the development path for fusion are cutting-edge capabilities in computer simulations, computer-aided design, and optimization.  While recent advances in simulations, multi-scale analysis, PDE-constrained optimization, global optimization, and machine learning have been transformative for the fusion field, characterization of kinetic plasma physics and associated transport processes remains a grand challenge when it comes to advancement of fusion reactor designs.  This workshop brings together computational physicists and applied mathematicians to establish and foster active interdisciplinary collaboration to address computational challenges and optimization in kinetic plasma physics.

This workshop will include lightning talks and a poster session for early career researchers (including graduate students). If accepted, you will be asked to do both. In order to propose a lightning session talk and a poster, you must first register for the workshop, and then submit a proposal using the form that will become available on this page after you register. The registration form should not be used to propose a lightning session talk or poster.

The deadline for proposing is January 7, 2024. If your proposal is accepted, you should plan to attend the event in-person.
