Price lab funded through part of a $5.2 million NASA project “InVADER: In-situ Vent Analysis Divebot for Exobiology Research”, for “Furthering the understanding and exploration readiness of terrestrial and planetary underwater vent systems”. Funding is now available for one Ph.D. student to join the Price laboratory over the next 4 years. See project description here. This student will be responsible for collection and analysis of hydrothermal vent fluid and precipitate samples collected from the Axial Seamount on the Juan de Fuca Ridge, in support of the InVADER objectives. The SoMAS graduate student application should be received by October 1st for the Spring semester or January 15th for the Fall semester, so don’t delay! Please contact Dr. Price if you are interested in applying and you meet the qualifications for admission listed through the application link above.

The Price lab is also looking for undergraduate student volunteers who are interested in assisting with cultivation of arsenotrophs – microbes who oxidize or reduce arsenic for energy and growth. Samples are in hand and ready for inoculation. Please contact Dr. Price if interested.


My research focuses on element cycling in the hydrological cycle, including:

  • Geochemical evolution of hydrothermal vent fluids, particularly shallow-sea vents.
  • Cycling of toxic elements in coastal marine environments, either naturally occurring or anthropogenic.
  • Environmental geochemistry, emphasizing source, fate, flux, transport
 and bioaccumulation of toxins.
  • Mobilization mechanisms and fate of arsenic in groundwater aquifers.
  • Abiotic vs. biotic (microbial) processes across redox gradients.
  • Shallow-sea analogs for early-Earth conditions and the origin of life.

Detailed Research Interests

shallowseavent1My research interests generally focus on element cycling in the hydrological cycle. As such, I am interested in a wide range of topics. However, my primary focus is on the geochemical evolution of hydrothermal vent fluids, particularly for shallow-sea vents, and the consequences this has for toxic metal cycling, bioaccumulation and microbial communities in these important coastal environments.

Shallow-sea hydrothermal vents are generally defined as occurring at a water depth < 200 m, a depth which marks the deepest extent of the photic zone and coincides with a large change in the slope of the seawater boiling curve. Their easy accessibility, relative to deep-sea hydrothermal systems, makes them excellent natural laboratories to study a wide range of chemical, physical, and biological processes. I’ve undertaken several research projects related to these types of hydrothermal vents. Click the link to see a brief description:

My research is not limited to hydrothermal vent research. I’ve also worked on several projects focused on understanding arsenic cycling in southwest Florida. Click here to learn more.
