What are the environmental conditions that form carbonates?
We are using Great Salt Lake as a living geomicrobiology laboratory.
Research
Research with Dr. Frantz combines field-based studies, sampling, chemical/geochemical analyses, laboratory-based experimental approaches, and computational modeling to understand the interactions between microorganisms and their environment, particularly in times of climate change. Dr. Frantz studies both modern environments and periods of extreme climate in the rock record.

GSL Microbialite Observatory
Microbial Carbonates
How do microbes build rock?
What can stromatolites and other microbialites tell us about past environments and climate?
Rotten Ice
What's happening to sea ice in the Arctic?
How are microbes involved?
Student-Driven Projects
Students working with me have done projects ranging from bacteriophage isolation to models of local air quality.
I may not have the answers, but I'm happy to help you find them.
