Associate Research Physicist

Princeton University
Princeton, NJ 08540


The Princeton Plasma Physics Laboratory seeks to fill a postdoctoral research position in the ITER & Tokamak Department for the development of real-time plasma control strategies for scenario optimization and disruption avoidance on the KSTAR tokamak. The successful candidate will work within a team to expand diagnostics and calculations available in the KSTAR real-time control system, and to design, simulate, and test model-based control algorithms. The appointment will be based in Princeton.


The successful candidate will work within a team to develop control-oriented models for plasma equilibrium and profile evolution and model-based control strategies to optimize performance and avoid disruptions. The candidate will also contribute to integrating new diagnostics and calculations within the KSTAR Plasma Control System and perform closed-loop integrated modeling simulations. The candidate will also experimentally test new control strategies on the KSTAR tokamak, located in Daejeon, Korea. The work includes developing fast reduced models for magnetic equilibrium, heating and current drive sources using neural networks and machine learning methods. We are looking for a highly motivated scientist, a team player and an excellent communicator who will collaborate closely with the onsite team at PPPL and researchers and engineers at KSTAR to develop and successfully apply plasma control tools. The position is at the post-doctoral level.


The successful candidate will be based in Princeton and is expected to occasionally travel to KSTAR and/or other national and international fusion facilities for joint experiments, workshops and conferences


Education and Experience:


Applicant should have a Ph.D. in plasma physics, control engineering, or related fields. Preference will be given to candidates with experience in tokamak physics and real-time control applications.


Knowledge, Skills and Abilities:


Familiarity with time-dependent simulations, including integrated models like TRANSP, as well as system identification and model reduction techniques, is highly desirable. Experience with machine learning, control algorithm design, and real-time algorithm implementation is desired. Experience with the General Atomics Plasma Control System or similar software is desirable but not essential.
