Research Projects:
1. How reef fish mimics are maintained in coral reef ecosystems, including: the role of avoidance learning in aggressive mimicry, the importance of perceptual ability by duped individuals, the role of colour changes in mimicry.
2. Signal design in multispecific interactions; including whether clients in cleaning interactions recognise cleaner organisms by their colour.
3. The evolution and signal design of aposematically coloured nudibranchs.
