Biography

Dr. Justin Rizzari is a Fisheries Scientist. He joined the School of Life and Environmental Sciences at Deakin University as a Lecturer in Fisheries in 2018. Justin has a Bachelor of Science in Marine and Coastal Resources from Texas A & M University – Corpus Christi. In 2011, he moved to Australia and completed a Postgraduate Diploma of Research Methods in Tropical Marine Ecology and Fisheries Biology at James Cook University (JCU). In 2015, Justin then went on to complete his PhD in Marine Biology at JCU. Prior to joining Deakin, he was a postdoc at JCU where he worked on modelling the interactive effects of benthic habitat change and marine reserves on coral reef fishes in the Philippines. After that he was a research fellow at the University of Tasmania, specialising in the high-value southern rock lobster and giant crab fisheries. Justin’s research interests span a diverse portfolio encompassing fisheries biology, quantitative fisheries science, assessments of commercial and recreational fisheries, marine conservation, spatial ecology, and the impacts of global change on fisheries. He also has a strong research interest in elasmobranch communities.
