Dr. Kara E. Yopak’s (née) research focuses on the evolution of neural systems, particularly how brains have diversified within some of the earliest vertebrate groups, namely sharks, skates, rays, and chimaerids, a group collectively referred to as Chondrichthyans. Dr. Yopak received her B.A. in Biology (with a specialization in marine science) from Boston University in 2002 and completed her PhD at the University of Auckland in New Zealand in 2007. For her PhD and beyond, Dr. Yopak’s research has focused on comparative neuroanatomy within the clade of cartilaginous fishes, and how the development of major brain areas vary between species in conjunction with the adaptive evolution of their sensory and motor systems. She has explored a variety of traditional and novel techniques to explore questions related to brain evolution of sharks and their relatives, including magnetic resonance imaging (MRI). Her data suggest that brain organization and the relative development of major brain structures reflect an animal’s ecology, even in phylogenetically unrelated species that share certain lifestyle characteristics, a pattern similarly documented in other vertebrate groups.

She is currently working within the Neuroecology Group, within the School of Animal Biology at UWA. Here she is exploring a multitude of questions relating to brain development, including how the brain, major brain components, and cell classes within these brain components scale across this unique group of animals. This work will potentially highlight a developmental plan that originated at least as early as cartilaginous fishes and may have been carried through evolutionary time to mammals. In addition, she is investigating whether alterations during early development in these animals can lead to changes in brain development, and by extension cognitive capabilities. This work could have far reaching implications for preservation of Australia’s biodiversity, particularly for improving survival strategies for captively-reared endangered species.
