TEDxAberystwyth 2018 speaker
Dr Roger Santer is a lecturer in zoology at Aberystwyth University. He has investigated the sensory systems and behaviour of a variety of invertebrates, including air movement sensitivity in arachnids, and motion vision in swarming locusts. He currently investigates colour perception in biting flies, with a view to optimising devices to control the diseases they spread.
We are surrounded by a variety of beautiful colours, but we might not realise that those colours are perceptions generated by our nervous systems. As such, different organisms perceive colours rather differently. His talk will explain how colour perceptions are generated, and how they vary across species. He shared how understanding fly colour perceptions can help us build more effective devices to control them.
