I am broadly interested in all aspects of colour and its functionality in biological organisms. As an optical physicist, the primary focus of my research to date has been the structural colours that are observed in an abundance of animal and plant systems. My current project will seek to provide new insights regarding the evolution and taphonomy (processes of decay and fossilisation) of scales and 3D photonic crystals in insects (primarily beetles).
