The major focus of my research is genetic control of morphogenesis - how genes control shape. One can study this huge question of biology in many ways using diverse model systems and exploratory techniques. I generally use molecular genetic techniques.
In 2007, I initiated an investigation into the development of the patagium in the southern flying squirrel, Glaucomys volans. A patagium is a thin flap of skin that stretches between the forelimbs and hindlimbs (see figure). Flying squirrels don’t really fly; they use the patagium as a parachute to glide from tree to tree. Other groups that have patagia are bats, flying lizards, flying lemurs, and gliding possums.
Little is known about development of the patagium or why it forms uniquely in bats, flying lizards, lemurs, possums, and squirrels. I hope to describe the formation of the patagium in G. volans and identify genes involved in its development. These genes are likely to be conserved in other species that possess a patagium so that once identified in flying squirrels, I can test expression of these genes in other gliding species. This knowledge will inform us about evolution of a unique structure that sets gliding species apart from almost all other mammals.
Of additional interest, G. volans has an extra rod of cartilage that extends laterally out from each wrist and helps to support and extend the leading edge of the gliding membrane. This structure, the styliform cartilage, is unique to the flying squirrels and its formation is likely to be related to development of the patagium. How is the styliform cartilage specified and formed? I hope to discover the mechanism of development of this unique anatomical structure.
