I am the senior scientist for solar physics in NOAA's National Centers for Environmental Information, leading the effort to calibrate data from the Solar Ultraviolet Imager (SUVI) on NOAA's GOES-R line of spacecraft. I also serve as lead scientist for other solar image data products used by NOAA including observations of solar magnetic fields from the Global Oscillation Network Group (GONG) and the Solar X-Ray Imager (SXI) on the previous line of GOES spacecraft.
Prior to joining CIRES and NCEI in Boulder, I worked at the Royal Observatory of Belgium, where I served as Principal Investigator for the SWAP solar imager on the European Space Agency's PROBA2 spacecraft. I am a Co-I for the Extreme-Ultraviolet Imager (EUI) on ESA's Solar Orbiter mission and ESA's formation-flying PROBA3 coronagraph mission.
My research interests include determining how to better calibrated and utilize observations of the sun's atmosphere, the solar corona, and using observations of the corona to better characterize the physical processes that shape and heat it. I am also interested in the processes that cause and drive huge eruptions on the sun that can lead to severe space weather effects in the near-Earth environment. Of particular interest is the process of magnetic reconnection, which can liberate vast amounts of energy stored in the sun's magnetic field to drive these events, which was the subject of my Ph.D. thesis and an ongoing line of research I am working on.
You can find the SUVI data I have been working on here.
