My research lies at the interface of molecular genetics, developmental biology, and evolution. In broad terms, I am interested in genetic and developmental events that underlie the evolution of animal form. I use organisms that occupy key phylogenetic positions in the chordate lineage: amphioxus, a cephalochordate that is the closest living relative to vertebrates; lampreys, the simplest living vertebrates; and sharks, the simplest vertebrates that have jaws and limbs. By cloning and characterizing developmentally important genes from these organisms, my lab is able to correlate gene duplications and the acquisition of novel gene expression domains with morphological innovations that occurred during early vertebrate evolution.
