Neuroethology
of Distributed Vision

Although most research on visual processing has been conducted on animals with a pair of eyes on their head and a centralized nervous system, we have much to learn from animals with very different sorts of visual systems. For example, some invertebrates have dozens of image-forming eyes and decentralized nervous systems. We are studying how these animals process visual information and control visually-influenced behaviors. In particular, we are studying the neuroethology of many-eyed molluscs such as scallops and chitons. Pictured above: a shell plate from a chiton with shell eyes.

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. Consequently, we are studying the co-evolution of physiological components of animals, such as their sensory, nervous, and locomotory systems. Pictured above: scallop species that differ in their abilities to see and swim.

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. Pictured above: the eyes and blue mouthparts of a porcelain crab.
