I am interested in x-ray and extreme ultraviolet radiation from high temperature plasmas. In particular I study spectroscopy which can be used to infer plasma conditions, such as electron temperature and density, based on different line ratios and also be used to study impurities within the plasma. Currently I am fielding three extreme ultraviolet spectrometers on the NSTX-U device at Princeton Plasma Physics Laboratory for impurity monitoring and assessing of wall conditioning techniques.
