Dr Darrell Kemp completed his PhD at James Cook University in 2002, and has since pursued postdoctoral research at the University of Stockholm, Sweden, and Arizona State University, USA. He is generally interested in evolutionary biology, and his research is aimed at understanding why male and female animals differ in many aspects of their behaviour and appearance. Dr. Kemp has studied a range of animals, including fish, lizards and insects, but focuses primarily on tropical butterflies because these animals offer excellent opportunities for studying evolution. He has authored over 40 refereed scientific publications, numerous popular articles, and presented findings at conferences throughout Australia, Europe and North America. Until recently Dr. Kemp was an Australian Research Council funded research fellow, based at James Cook University, Cairns. He is now in Sydney.
