Professor Nicholas Roberts


I am primarily interested the detection of light and colour in nature. My research is focused on investigating optical mechanisms that underlie sensory abilities such as polarization vision and the evolution of the bio-optics of signaling and photoreception. My work adopts a broad intra- and inter-disciplinary approach, using a combination of physics based techniques (microspectrophotometry, laser tweezing, optical modelling and X-ray scattering) and behavioural studies (operant conditioning and novel optomotor techniques). Ultimately, I want to understand how visual information helps guide aspects of animal behaviour.
