Personal profile

Research interests

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.
