Eric Warrant is a world leader in the fields of neuroethology, comparative vision, and visual ecology, and actively leads and serves these fields on the international stage. He is the world authority on vision and navigation in extremely dim light and has elucidated the optical and neural principles that dramatically improve visual performance in nocturnal and deep-sea animals. These have been applied in novel camera technologies. Warrant has also discovered the sensory mechanisms that enable nocturnal animals to navigate while homing or migrating, including the magnetic and stellar compasses of the iconic and endangered Bogong moth.
