Biographical Summary

Nick Pester received a Ph.D. in Earth Science from the University of Minnesota in 2012. His research involves experimental and field investigations pertaining to the geochemistry of hydrothermal reactions. Specific studies currently include: the chemical evolution of deep-sea hydrothermal vent fluids and the impacts on associated biota, the abiotic synthesis and stability of organic compounds, potential reservoir effects related to geological carbon sequestration or carbon capture and storage, the effect of high salinity fluids on subsurface reactions, and the effects of fluid chemistry on sub-critical crack growth in deforming materials.

Research Experience

Experimental Research

  • High-temperature/pressure fluid-mineral and fluid-fluid phase equilibria relevant to natural hydrothermal systems
  • Experimental design and use of hydrothermal reaction cells/techniques and high-temperature/pressure flow systems
  • Volatile gas equilibria and hydrocarbon formation in geothermal systems
  • Geochemical effects of carbon capture and storage processes
  • Stability of hydrocarbons and biomolecules in fluid-mineral systems
  • Chemical effects on subcritical crack growth in glass/minerals
