Dr Keller Kopf has research interests in freshwater and marine fish ecology, fisheries science and organismal biology. He is currently undertaking a postdoctoral research fellowship helping to establish a Fish Ecology Collaborative Research Unit at Charles Sturt University. He has worked on ecological responses to altered river flow regimes in the Murray-Darling Basin and maintains active research on life-history and population biology of open ocean fishes.
His research integrates fundamental biology and ecology with applied aquatic biodiversity conservation and natural resource management. Keller is interested in how environmental and anthropogenic factors shape aquatic organisms, populations and ecosystems. This work has stimulated a recent interest in other research areas including macroecology, invasive species, body size scaling relationships and human-induced changes to biodiversity reference points.
Prospective Honours, Masters, or PhD students interested in any of the above topics are welcome to contact him.
Keller is a member of the Fish Ecology Collaborative Research Unit (FECRU)
