Dr Keller Kopf is a research fellow with interests in fish ecology and the management and conservation of freshwater and marine ecosystems. His work combines field, laboratory and modelling approaches to address applied and fundamental research questions—mostly related fish and helping to inform government policy and decision-making on sustainable use of aquatic ecosystems and the benefits to people.
The focus of his recent work has been on invasive species ecology, environmental flows, and life-history traits. His research spans large open ocean fish communities to small rivers and streams. This work has led him to think about drivers of biodiversity and its loss across diverse freshwater and marine environments. In this area, he is pursuing projects focused on body size scaling patterns, macroecology and the roles of invasive species in aquatic food webs.
Keller helped to initiate the Fish Ecology Collaborative Research Unit (FECRU) led by Dr Paul Humphries.
He is currently accepting Honours and PhD students interested in invasive species ecology and management—especially the ecological effects of common carp and the application of koi herpes virus biocontrol in Australia.
