Personal profile
I am an applied conservation ecologist with a strong focus on freshwater fishes and aquatic ecosystems, but I have also worked on herpetofauna or invertebrates. My research focuses on various challenges to securing biodiversity and ecosystem services in a rapidly changing and anthropogenically influenced environment, such as managing habitat decline, restoration approaches, maintaining connectivity, invasive species, fisheries management, and protecting aquatic fauna around water infrastructure, mainly related to irrigation or hydropower. I am conducting a PhD on fish screens at Australian water diversions.
