The eyes of scallops are single-chambered like the camera eyes of vertebrates and cephalopods, but use a mirror for image-formation instead of a lens.
Joshua Paul Stone Assistant Professor	Ecology, Oceanography, Fisheries	I am an aquatic ecologist broadly interested in how humans are affecting freshwater and marine ecosystems, especially through climate change. Specifically, I study how zooplankton populations have been changing, and how those changes affect food web interactions, both within the zooplankton and then up to fish and higher trophic levels. I care how humans are affecting aquatic food webs and what that means for the future of aquatic resources.
Dr. Johannes Stratmann Professor	Plant Science; Plant responses to stress with emphasis on herbivory, Signal transduction: MAP kinases; regulation of targeted proteolysis	We study molecular mechanisms of stress signal transduction in plants.

Plants undergo two major developmental transitions after germination: from juvenile to adult vegetative and then vegetative to reproductive form. Correct timing of these transitions is essential for survival and reproduction of the plant. The miR156-SPL module is particularly important during the regulation of both developmental transitions, each of which are under the influence of internal and external cues.
