Bob was awarded his PhD from The Australian National University in 2004. Following the completion of postdoctoral fellowships in the United States and Finland, Bob returned to Australia and joined Monash in 2006.
Bob's research group focuses on the evolution of animal mating systems and behaviour, and how investment in sex influences reproductive strategies and biological diversity. In recent years, Bob has expanded his research to investigate the impacts of environmental change on animal behaviour and the evolutionary process. Members of Bob's group conduct research on a wide range of species, from insects to fish.
