Dr. Andreas Kleiner is a postdoctoral research associate at the Princeton Plasma Physics Laboratory. He received his B.Sc. (2012) and M.Sc. (2014) degrees in Physics from the Technical University of Darmstadt, Germany, and his Ph.D. (2019) from the Swiss Federal Institute of Technology (EPFL) in Lausanne. His doctoral research was conducted at the Swiss Plasma Center of EPFL, where he investigated the nonlinear behavior of macroscopic instabilities in tokamak plasmas. This included the coupling of ideal and resistive modes in the plasma core, as well as saturated modes at the plasma edge in quiescent H-mode regimes.

At PPPL he is working with Dr. Nate Ferraro on the modeling of magnetohydrodynamic modes related to the edge pedestal in spherical tokamaks to predict pedestal parameters for ELM-free plasma discharges. He is also interested in exploring quiescent H-mode regimes in spherical and large aspect ratio tokamaks.
