Research Description: Evolution of Germ Cell Specification and Reproductive Systems Our lab is interested in the evolution of early embryonic development, with a focus on the germline and the evolution of the mechanisms that specify these cells during embryonic development. We use molecular genetic developmental analysis, histological analysis, and experimental embryology to study germ cells and gonad development in several different arthropod model systems. Our ultimate goal is to improve our understanding of which developmental mechanisms may have been basal to arthropods, and ultimately to metazoans, and how these mechanisms may have changed throughout evolution.
