Curriculum Vitae
Nick Peng


  • Biogeochemistry and Geochemistry
  • Climate Change
  • Coastal Processes
  • Earth Systems
  • Marine Ecology
  • Oceanography


Microbes interact among themselves and with the physical world. They respond to environmental changes in ways that shape the physical world in turn. I develop, apply, and integrate novel methods in microbial ecology and geochemistry to study these intricate relationships found in marine environments.
