Starting as an undergrad at Brown University, I worked with Casey Dunn on the evolution of a group of free-swimming colonial hydrozoans called siphonophores. This work sparked my interest in the evolution of diverse forms and the interaction between genetic and cellular mechanisms that contributes to these forms. In addition to studying jellyfish evolution and development in the Dunn lab, I developed phylogenetic software, called SOWHAT, which statistically tests evolutionary hypotheses. Starting in 2015 I will be a graduate student in the Extavour lab, in the OEB graduate training program.
