Dr Robert Harcourt is leader of the Marine Predator Research Group at Macquarie University. He has authored over 320 scientific publications and written 2 books. 

Dr Robs primary interests of expertise are in marine conservation, behavioral ecology of marine predators, and marine observing. We talk about all things marine from Australia's increasing shark encounters, debunking some Seaspiracy facts and his thoughts on the future of the ocean. We discuss how to implement change at both a personal level and at a government policy level. We also discuss how warming of the ocean is changing aquatic animals behavioural patterns, sending species further south due to warming water temperatures.
