Curriculum Vitae:

Charles Malone

Education
  • Ph.D., Physics, University of Windsor, Windsor ON, Canada (2003)

Research Interests
  • UV/visible/near-IR spectroscopy of planetary atmospheres, particularly auroral physics: Titan, Earth, Io, Jupiter, Saturn, etc.
  • Laboratory studies of electron and ion collisions with atomic and molecular species, using impact induced emission spectroscopy, electron energy loss spectroscopy, and time-of-flight (metastable) spectroscopy to investigate fragmentation dynamics, cross sections, and predissociation yields, relevant to planetary atmospheres and astrophysical environments, radiation damage in biological materials, and to environmental pollution.
  • Development of non-standard target production (i.e., neutral, ground state H, H2(v), O, S, OH, etc.) and methods in cross section determinations, such as complete glow imaging, differential surfaces, and molecule trapping.
  • Electron-cluster interactions involving excitation of neutral fragments in rare gases and simple molecules such as water.
