Paul is a Project Scientist in the High Altitude Observatory at NCAR. He received his PhD on the spectral emission of non-Maxwellian plasmas from the University of Strathclyde in the UK in 2005. He has since worked as a Postdoctoral Research Scientist at Columbia University, a Research Associate Professor at George Mason University, and as a Support Scientist at NASA Goddard Space Flight Center. He joined HAO in 2014.
Paul has a background in atomic physics and the spectral emission from astrophysical plasmas. His research focuses on dynamic events in the solar atmosphere. In particular, on how mass and energy is transported from the lower atmosphere to the solar corona. This research uses observational data from many space-based solar observing instruments. He is currently a member of the Interface Region Imaging Spectrograph (IRIS) science team.
In addition to solar research, Paul has also conducted research in the fields of supernova remnants, molecular clouds, and comets.
