Molecular evolution of self-assembling protein photonic structures in molluscs and optical characterization of the sophisticated roles they play in camouflage and photosynthetic symbiosis; cellular and biochemical mechanisms of dynamic camouflage; characterization of
the open ocean light environment in which animals have evolved sophisticated camouflage; spectral changes during twilight and their effects on visual ecology.
