Dr. Kara Yopak - Science and Education adviser
Kara Yopak received her B.A. in Biology (with a specialization in marine science) from Boston University and completed her PhD at the University of Auckland in New Zealand in Sensory Neuroethology, before completing postdocs at the University of California San Diego and the University of Western Australia. Over the last 15 years, she has focused on broadening our understanding of the adaptive, developmental, and phylogenetic forces acting on evolution of the brain of sharks and their relatives.
In the ZoMBiE Lab (Zootomical Morphology of the Brain and Its Evolution) at the University of North Carolina Wilmington, Kara and her students investigate the evolution of neural systems, particularly the ways in which variation in brain size, structure, and cellular composition underlie complex behaviors and cognitive capacity in fishes. With a collection of over 1000 brains across 50 orders of fishes (they’re not called the ZoMBiE lab for nothing), they utilize a wide range of techniques, including magnetic resonance imaging (MRI), diceCT, flow cytometry, and histology, to explore variation in the brain within and across species. Differences in the brain are allowing the ZoMBiE Lab to make predictions about sensory and behavioral specialization across species, highlight transitions in life-history stages within a single species, and predict the neural consequences of environmental change.
