Work in the McCauley lab is focused on gaining an understanding of how the origin and evolution of neural crest cells has contributed to vertebrate evolution. Recent work has been focused on deciphering how changes in gene function has led to changes in the head skeleton and the peripheral nervous system, using the sea lamprey as a model for comparison with developmental mechanisms among jawed vertebrates, since lampreys and their relatives diverged from gnathostome (jawed) vertebrates early in vertebrate evolution.
We have also recently begun to investigate the feasibility of using genetic modification to impact control of the sea lamprey, Petromyzon marinus, since this animal is now an invasive species found throughout the Laurentian Great Lakes. Developing strategies to manipulate the sea lamprey genome for ecosystem management purposes may also facilitate understanding and manipulation of molecular mechanisms regulating the development of this interesting model organism.
