  • Evolution
  • Developmental biology


Medusozoans are a clade of cnidarians that include hydrozoans (Hydra, hydromedusae and hydroids), scyphozoans (true jellyfish), cubozoans (box jellies) and staurozoans (stalked jellies). Medusozoans are relatively simple in terms of their component parts, yet they display a remarkable diversity of forms and life cycles. The tremendous diversity of medusozoans has been appreciated for centuries, yet many questions remain unanswered with regard to the evolutionary patterns and processes underlying this diversity. With new advances in phylogenetics, genomics and developmental biology, it is now possible to re-address these outstanding questions using modern approaches. My lab is using genomic approaches to investigate the evolutionary relationships of medusozoans and the developmental mechanisms responsible for the diversity of medusozoan forms.
