My research concerns the evolutionary development of teeth and jaw amongst early vertebrates, especially in placoderms (armored jawed fish). The morphology and histology of gnathal elements of placoderm fishes reveals a wealth of functional morphological and evolutionary developmetal information, lending to broad inner group comparisons and comparisons with very distantly related lineages or groups that may have few outward resemblances; together challenging the definition of 'true' teeth and shedding light on the evolution of teeth and jaw.
