Student Profile – Justine J. Allen
Brown Neuroscience / MBL Program in Sensory Physiology and Behavior

I am interested in changeable, adaptive camouflage and study a cephalopod model, the European cuttlefish Sepia officinalis. I am particularly focused on the neurophysiology of this animal’s three-dimensional papillae, elements that allow for dynamic skin texture change, and the visual cues that evoke their expression. Laboratory experiments are complemented by underwater photography and videography, and I am an AAUS certified scientific diver. At the MBL, I am working with Dr. Roger T. Hanlon.
