Visual Ecology of Marine Invertebrates
The visual systems of animals vary in form and function. Consequently, different kinds of animals perceive similar surroundings in dissimilar ways. By characterizing the spatial resolutions, spectral responses, and temporal dynamics of visual systems, we can identify the visual cues that influence how animals detect predators and prey, hide themselves from detection, and navigate through their environments.
We study the visual ecology of shallow-dwelling marine invertebrates including a variety of molluscs and crustaceans. |
Neuroethology of Distributed Vision
Although most research on visual processing is conducted on animals that have a pair of eyes on their head, we have much to learn from animals with visual systems that deviate from this familiar arrangement. For example, some invertebrates have visual systems that include dozens of image-forming eyes. We are studying how these animals use their relatively simple nervous systems to integrate and process visual information. In particular, we study the neurobiology of many-eyed molluscs such as scallops and chitons.

Co-evolution of Complex Physiological Traits
From an integrative and organismal perspective, the function of any physiological system is linked inextricably to the functions of other physiological systems. Studying the functional relationships between physiological systems is necessary if we are to understand how organisms evolve as integrated wholes rather than collections of disparate parts. To better understand the histories of complex traits, we are studying how physiological systems, such as sensory systems and locomotory systems, co-evolve.
