Research Interests In my lab, we are interested in understanding the developmental evolution of our own subphylum, the vertebrates. To do this, we study developmental gene expression, regulation, and function in three model organisms; lamprey, amphioxus, and zebrafish. Lamprey, a jawless vertebrate, is the most basal vertebrate amenable to experimental manipulation at embryonic stages. Amphioxus is the most basal extant chordate and is thought to closely resemble the invertebrate ancestor of the vertebrates. Zebrafish, a teleost, is one of the most experimentally tractable vertebrate model systems. By comparing lamprey and amphioxus development with that of zebrafish, and other vertebrates like frog and salamander, we aim to reconstruct the genetic and developmental changes underlying the earliest events in vertebrate evolution.
