Ecological Chemistry of Ocean Health
Research
Our research probes the interactions between marine organisms and their geochemical environment by integrating geological, chemical, and biological perspectives. In doing so, our research encompasses several domains of life spanning bacteria to corals, explores elements both essential (e.g., oxygen) and detrimental (e.g., chromium) to life, and spans diverse geochemical niches (from coral reefs and the deep-sea on Earth to rock varnish on Mars).
