Research Interests

I study the relationship between development and regeneration in various organ systems including the limb, the lung, the skin and the nervous system. The guiding principle of this research is that by comparing the signaling molecules that operate in these two processes we can determine whether there are any fundamental differences (is regeneration a process of re-development?) and whether we can induce regeneration by re-awakening developmental pathways. Much of this work is centered on one signaling pathway, that of retinoic acid and the organisms used range from axolotls (the champion of regeneration) to mice. Most recently we have discovered that the spiny mouse can regenerate its skin wounds perfectly by replacing hairs, sebaceous glands, dermis, smooth muscle and skeletal muscle and much of our work is now concerned with what seems to be a remarkable regenerating mammal.
