Vertebrate paleontology with emphasis on morphology, phylogeny, paleoecology, and taphonomy of fishes. Current research projects include anatomical and phylogenetic studies of Paleocene and Late Cretaceous marine and freshwater teleosts, studies of temporal variation in the morphology of fishes preserved in varved lake sediments of Eocene age, analysis of taphonomic evidence for cause of death and preservation in fossil fishes, and morphological and phylogenetic studies of Silurian and Devonian jawless fishes and early jawed fishes such as acanthodians and early relatives of sharks.
