Julia Diaz - How stressed is the ocean? Exploring marine ecosystem health at the intersection of microbiology and geochemistryFrom plankton to people, every living thing experiences stress. Stress often carries a negative connotation, but psychologists have shown that people can become healthier by believing that stress is helpful. Similarly, microbes in the ocean experience stress in order to adapt to challenging environmental conditions. My lab studies how marine microorganisms interact with their geochemical environment through diverse stress responses in order to cope with large-scale anthropogenic disturbances. In this way, our results reveal how the oceans may evolve during this time of profound global change. A key aspect of this work involves the discovery of previously unrecognized enzymes, or biological catalysts, which form the basis of microbial stress responses.
