     Vision plays a fundamental role in guiding behaviour such as foraging, predator avoidance, navigation, and mating. Visual aspects of these behaviours represent important domains of inquiry in biological research. My laboratory takes a multidisciplinary approach to understanding how vision, specifically the retina, develops, and functions, and provides critical information concerning the visual environment. I have had a career long commitment to maintaining an environmental biology perspective in my research program. All of our research relates directly to the visual ecology, evolution and behaviour of fishes. My research program uses an innovative, multi-faceted approach to investigating the visual system in several targeted areas: (1) Phenotypic variation in color vision in gradients of environmental light; (2) Evolutionary aspects of retinal ontogeny – alternative life history strategies and visual behaviour; (3) Evolutionary aspects of retinal information processing – color and polarization; and (4) Visual communication and environmental quality. My lab offers excellent opportunity for postdocs and graduate students interested in visual ecology, evolution and behaviour of fishes, and offers outstanding facilities including - molecular biology suite, confocal/two photon microscopy, electrophysiology suite, microspectrophotometry, behavioural observation lab, and field gear and photonic instrumentation for field measurements of environmental light.
