Dr. Albert Mollén is a Postdoctoral Research Associate in the Theory Department of the Princeton Plasma Physics Laboratory. In 2015 he earned his Ph.D. at Chalmers University of Technology in Sweden, for work on kinetic modeling of impurity transport in magnetically confined fusion plasmas. The work included the development of semi-analytical models of quasilinear impurity transport in axisymmetric plasmas and models of collisional transport in non-axisymmetric plasmas. During this work he performed gyrokinetic simulations with the GYRO code and drift-kinetic calculations in 3D plasmas with the SFINCS code.

Dr. Albert Mollén later joined Max Planck Institute for Plasma Physics in Greifswald, Germany, as a postdoctoral researcher and continued to model the transport of impurities in stellarator plasmas. In particular, he studied variations of the electrostatic potential along flux-surfaces and their impact on the impurity transport. As a part of this work he implemented the corresponding equations in SFINCS.

At PPPL, he is involved in the “High-Fidelity Whole Device Modeling of Magnetically Confined Fusion Plasmas” project, a part of the Exascale Computing Project, and work in the XGC group together with Dr. Robert Hager and Prof. Choong-Seock Chang.
