Curriculum Vitae:

Laurie Barge

  • Ph.D., Geological Sciences, University of Southern California (2009)
  • B.S., Astronomy and Astrophysics (Minor in Physics), Villanova University (2004)

Research Interests
  • Understanding geochemical disequilibria that arise on wet rocky planets and provide chemical energy for life, leading toward understanding habitability on Mars, Europa, Enceladus, and exoplanets.
  • Chemical gardens and other self-assembling inorganic systems (including hydrothermal chimneys).
  • Hydrothermal vent systems: electrochemistry, organic chemistry, spectroscopic methods and science operational strategies for exploration and analysis.
  • Iron mineral chemistry: iron sulfide / hydroxide synthesis, minerals as catalysts for organic synthesis and redox.
  • Developing fuel cells and electrochemical technologies to simulate geological and planetary systems.
  • Outreach and mentoring for women / minorities in STEM. Particular focus on women in space science and integrating community college and other non-traditional students into NASA-funded research.
